arrays of structures
An array is a collection of variables of the same type referenced by a common name. A structure groups variables of different types. An array of structures combines these concepts by creating an array where each element is a structure. For example, an array of fraction structures could be defined to hold multiple fractions. Each structure element in the array contains a numerator and denominator integer. The entire array of structures occupies a contiguous block of memory with each structure taking up the same amount of space. Individual structure elements can then be accessed using the array index and dot notation.
String
This document discusses strings and string handling functions in C programming. It introduces strings as arrays of characters, and describes how to read and write strings using input/output functions. Examples are provided for programs that count characters in a string and reverse a string. Common string handling functions are explained, including strcmp(), strcpy(), strcat(), strlen(), and others. The document concludes with assignments for students to write programs implementing these string functions.
Array
An array is a group of consecutive memory locations that share the same name and type. An array allows storing multiple values of the same type using a single name. Arrays have advantages like efficiently storing and processing large amounts of data. Array declaration specifies the array name, length, and data type. Array initialization assigns initial values to the elements at declaration time by enclosing comma-separated values in braces.
Python strings
This document discusses various string operations in Python including: finding the length of a string; accessing and slicing characters; the difference between strings and lists; converting case; checking character types; splitting strings; finding substrings; reading and printing strings; concatenation and repetition; iterating through strings with for loops; and common string methods like isalpha, isdigit, lower, upper, title, join, split, count, find, index. It also provides examples of problems involving anagrams, pangrams, unique characters, and removing duplicates from strings.
Arrays
This document discusses arrays in C programming. It defines arrays as ordered lists of homogeneous data elements stored in consecutive memory locations that can be accessed via indices. Arrays are classified as one-dimensional or multi-dimensional based on the number of indices. One-dimensional arrays are linear lists that can be declared with a size and data type. Multi-dimensional arrays have more than one index and can be two-dimensional like a matrix with rows and columns. Examples of declaring and using one and two-dimensional arrays in C code are provided.
Java -lec-6
Java arrays allow storing multiple values of the same data type. There are one-dimensional arrays, which store elements in a list, and multi-dimensional arrays, which can be thought of as tables with rows and columns. Methods are blocks of code that perform operations, and can take parameters and return values. Parameters can be passed by value, where the method gets a copy of the argument, or by reference, where changes to the parameter affect the original argument.
Anton Kasyanov, Introduction to Python, Lecture4
This document provides an introduction and overview of Python lists, tuples, dictionaries, and files. It discusses how lists can contain a grouping of similar items indexed from 0, how tuples are immutable lists, how dictionaries contain key-value pairs, and how to read files line by line in Python. It also assigns as homework to create a basic translation program that uses lists or dictionaries to translate words between two languages using a file-based dictionary.
Java arrays
An array allows you to store multiple values of the same type. It is like a spreadsheet with columns. You specify the data type of the array and the number of elements (size). Each element has an index position starting from 0. You can assign values to each position using arrayName[index] = value. Arrays make it easy to work with multiple values of the same type.

Chap 7(array)
The document discusses arrays in C programming. It defines an array as a group of related data items that share a common name, with each item indicated by an index number. One-dimensional arrays can be represented with a single subscript, while multi-dimensional arrays use multiple subscripts to reference elements by row and column. The document also covers declaring, initializing, and accessing arrays, including examples of one-dimensional, two-dimensional, and multi-dimensional arrays in C.
Arrays and Strings
1. Arrays allow storing of multiple elements of the same data type under a single name. They can be one-dimensional, two-dimensional, or multi-dimensional. Strings are arrays of characters terminated by a null character.
2. Common array operations include declaring and initializing arrays, accessing elements using indexes, and performing element-by-element operations. Strings have specialized functions for operations like length calculation, copying, comparison and concatenation.
3. Pointers allow working with arrays by reference rather than value and are useful for passing arrays to functions. Structures group together different data types under one name and unions allow storing different data types in the same memory space.
String handling(string buffer class)
StringBuffer implements a mutable sequence of characters that can be modified unlike strings. It has methods to modify the character sequence such as append, insert, delete and replace. It can grow dynamically as characters are added and its methods are used by the compiler to implement string concatenation with the + operator.
Java arrays
Access modifiers in Java define the scope of variables, methods, and classes. The four access modifiers are public, private, protected, and default. Public members are accessible everywhere, private within the class, protected within the package and subclasses, and default within the package. Arrays are objects that hold multiple values of the same type. One-dimensional arrays have a fixed length, and elements are initialized with default values. Multi-dimensional arrays are arrays of arrays. Two-dimensional arrays represent rows and columns. Array bounds cannot be exceeded, but the reference variable can refer to a new array. The arraycopy method copies arrays.

ARRAY
An array is a collection of data types that holds a fixed number of values of the same type. Arrays are declared with a data type, name, and size. They store elements in consecutive memory locations that can be accessed via an index. The length of an array is calculated as the upper bound index minus the lower bound plus one. Arrays can be one-dimensional, two-dimensional in the form of a matrix, or three-dimensional with additional indices.

6 arrays injava
An array is a container that holds a fixed number of values of the same type. Arrays in Java are created in three steps: 1) declare the array name and type, 2) create the array using new, and 3) initialize the array values. The length of an array is fixed at creation. Arrays can be one-dimensional, containing a list of values, or multi-dimensional, containing other arrays. Elements in arrays are accessed via an index with the first element at index 0.
String Handling
String objects are immutable in Java, so any operation that modifies a String value actually creates a new String object. The StringBuffer and StringBuilder classes provide mutable alternatives to String that have similar methods but do not create new objects with each modification. When a String literal value is used in code, it is stored in the String constant pool to promote reuse of these immutable objects.
C++ Arrays
An array is a collection of elements of the same type stored in contiguous memory locations that can be accessed using an index. Arrays allow storing multiple values as a single variable. One-dimensional arrays store elements in a list, while multi-dimensional arrays arrange elements in multiple dimensions. Elements are accessed using their position indices, which must be within the array bounds. Arrays can be initialized during declaration and values accessed using loops. Operations like input, output and searching are commonly performed on array elements.
Java chapter 6 - Arrays -syntax and use
An array is a container that holds a fixed number of elements of the same type. An array's length is established at creation and cannot be changed. Each element has an index number starting from 0. The document demonstrates how to declare, initialize, access, and copy array elements in Java. It also discusses multidimensional arrays.

Array
An array allows us to store multiple values of the same data type using a single variable name. It represents the data contiguously in memory. We declare an array by specifying its type, name and size. Individual elements can be accessed using indexes and assigned values. Arrays can be passed to functions along with their size.
Arrays Basics

Strings in Java
This document discusses strings and string buffers in Java. It defines strings as sequences of characters that are class objects implemented using the String and StringBuffer classes. It provides examples of declaring, initializing, concatenating and using various methods like length(), charAt() etc. on strings. The document also introduces the StringBuffer class for mutable strings and lists some common StringBuffer functions.
javastringexample problems using string class
Java strings are sequences of characters that are treated as objects. The String class provides methods to create and manipulate strings. Strings are immutable, so the StringBuffer and StringBuilder classes provide mutable alternatives. Key string methods include concat(), equals(), substring(), length(), and indexOf(). The StringBuffer class is synchronized and thread-safe, while the StringBuilder class is non-synchronized and more efficient for single-threaded use.
Fileoperations.pptx
The document discusses the difference between constructors and methods in Java. Constructors are used to initialize an object's state and must not have a return type, while methods are used to expose an object's behavior and must have a return type. Constructors are implicitly invoked, while methods are explicitly invoked. The Java compiler provides a default constructor if none is defined, but does not provide default methods. Constructors must have the same name as the class, but method names are more flexible.
Java string handling
This document discusses Java strings and provides information about:
1. What strings are in Java and how they are treated as objects of the String class. Strings are immutable.
2. Two ways to create String objects: using string literals or the new keyword.
3. Important string methods like concatenation, comparison, substring, and length; and string classes like StringBuffer and StringBuilder that allow mutability.

The document discusses processing strings in Java using the String, StringBuffer, and StringTokenizer classes. It provides details on constructing and manipulating strings, including obtaining length, retrieving characters, concatenation, substrings, comparisons, and conversions. It also covers the StringBuffer class for processing mutable strings, and the StringTokenizer class for extracting tokens from strings. Examples provided demonstrate checking palindromes, counting letters, using StringBuffer for output, and processing command-line arguments.
String handling
The document discusses string handling in Java. It covers:
1) Strings are immutable objects that cannot be modified, but new strings can be created from existing ones. StringBuffer and StringBuilder allow mutable strings.
2) Common string operations like comparison, searching, and concatenation are built into the language.
3) Methods like length(), charAt(), substring(), and trim() allow extracting characters from strings.
package
Packages in Java prevent naming conflicts, control access, and make classes easier to locate and use. A package groups related types and provides namespace management and access protection. Exceptions in Java handle runtime errors to maintain normal program flow. There are three types of exceptions: checked exceptions which are verified at compile-time; unchecked exceptions which are verified at runtime; and errors which are irrecoverable. Multithreading allows concurrent execution of program parts through threads, which can be created by extending the Thread class or implementing the Runnable interface.
StringBuffer.pptx
The StringBuffer class represents mutable sequences of characters. It is similar to strings but allows modifications by providing methods like append(), insert(), delete(), and replace(). StringBuffer has a default capacity of 16 characters that is increased automatically when more space is needed to store character sequences. It is used by the compiler to implement string concatenation with the + operator.
Strings In OOP(Object oriented programming)
The document discusses strings and string handling in Java. It covers the String and StringBuffer classes, basic string methods like length(), substring(), indexOf(), and replace(). It also discusses parsing strings with StringTokenizer and the differences between StringBuffer and String in terms of mutability and capacity. StringBuffer allows growing the string size while String is immutable.

Arrays allow the grouping of multiple values of the same type under a single name. An array is declared with a base type and size, and individual elements can be accessed via an index. Arrays are useful for organizing related data and can be passed to methods. Common array operations include initialization, accessing elements, searching, and sorting. Multidimensional arrays extend the concept to multiple indices.
ch06.ppt
Arrays allow us to organize multiple values of the same type into a single variable name. An array is declared with square brackets containing the number of elements, and individual elements are accessed via an index number. Arrays can be passed as arguments to methods, where the method can modify class-type elements but only sees the value of primitive-type elements. Array names are reference types, so assigning one array name to another makes them refer to the same array, and the == operator checks for identical references rather than identical element values.

array Details
Arrays allow us to organize multiple values of the same type into a single variable name. An array is declared with a base type and size, such as int[] grades = new int[100]. Individual elements in the array are accessed using an index from 0 to length-1. Arrays can be passed to methods by reference, allowing the method to modify the array elements. Multidimensional arrays organize data into rows and columns and are declared with multiple sets of brackets like int[][] table = new int[10][20].

The presentation starts with string handling. Then the concepts of inheritance is detailed. Finally the concepts of packages and interfaces are detailed.
Arrays
The document discusses one-dimensional and two-dimensional arrays in C++. It defines an array as a series of elements of the same type that allows storing multiple values of that type. For one-dimensional arrays, it covers declaring, initializing, and accessing arrays using indexes. Two-dimensional arrays are defined as arrays of arrays, representing a table with rows and columns where each element is accessed using row and column indexes. The document provides examples of declaring, initializing, and accessing elements in one-dimensional and two-dimensional arrays in C++.

It defines a contributor as someone who cares about others, takes responsibility, and prioritizes team success over personal gains. Contributors support their team, act ethically, and perform their work well. Society needs contributors to help improve education, create a better community, and aid in national development. In contrast, non-contributors avoid challenges, focus only on themselves, and have a narrow vision of success. The document emphasizes that stepping outside one's comfort zone is key to becoming a strong contributor.
Electrical engineering
Electromagnetic relays automatically sense faults and isolate faulty sections by opening circuit breaker contacts. There are two main types of electromagnetic relays: attracted armature and solenoid/plunger. Attracted armature relays use a counterweighted armature that bridges contacts when a fault increases current enough to attract the armature. Solenoid/plunger relays use a solenoid to attract a plunger that closes trip contacts when current exceeds the pickup value. Induction relays use electromagnetic induction to rotate a disc between electromagnets producing torque from alternating fluxes. Thermal relays use a bimetallic strip heated by overcurrent in a coil; the different expansion rates of the metals cause the strip to
computer organization
Data types can be stored in registers including numbers, letters, and symbols represented in binary-coded form. Common number systems include decimal, binary, octal, and hexadecimal. Complements are used in computers to simplify subtraction and logic operations. There are two types: r's complement and (r-1)'s complement. Micro-operations are elementary operations performed on data stored in registers, such as shift, count, clear, and load operations. They transfer data between registers or perform arithmetic, logic, or shift operations. Micro-operations are controlled by hardware that defines the register set and sequence of operations.

- 1. CONTENT Types of array String and StringBuffer Class Method of StringBuffer Class
- 2. Array • Array is similar type of elements and share a common name. • Syntax datatype variblename [ ] = new type [size of array] • Example int a [ ] = new int [7] •Types of array : 1) Single dimension array 2) Multi dimension array
- 3. Single dimension array • Syntax int a[ ] = new int [ 10 ] • An array using one subscript to represent the list of element is called Single dimension array. Multi dimension array • Syntax int a [ ] = new int [3] [3] row column • In Java , multi dimension array is actually array of arrays.
- 4. Stringclass • An obj of the string class represent a string of class. • String class belong the java.lang package which does not require the input-output statement. • Like , other classes string has constructor and methods. • Syntax : String s = new String (“hello”); System.out.println(s); String s1 = new String (s); String s = “hello world”; System.out.println(s);
- 5. StringBufferclass • The java.lang.StringBuffer class is a mutable sequence of characters. • A String buffer is like a string , but can be modified. • It contains some sequence of characters , but the length and content of the sequence can be changed through certain method calls. • They are safe for by multiple threads. • Syntax StringBuffer sb = new StringBuffer ();
- 6. DifferencebetweenStringandStringBuffer BASIS FOR COMPARISON STRING STRINGBUFFER Basic The length of the String object is fixed. The length of the StringBuffer can be increased. Modification String object is immutable. StringBuffer object is mutable. Performance It is slower during concatenation. It is faster during concatenation. Memory Consumes more memory. Consumes less memory.
- 7. Method of StringBuffer class METHODS Description SetLength ( int size) It is used to set the length of string. CharAt (int index) It returns the character at the specified index in a string. SetcharAt (int index , char ch) It is used to set the specified character at the given index. It replacing the old character at the given index. append (String s) It is used to append the specified string with this String. Insert (int index , String str) It is used to insert the specified String at the specified position. reverse( ) It is used to reverse the string. replace (int startindex , int endindex ,String str) It is used to replace the string from specified startindex and endindex.
- 8. getchars (int S , int E , char a[ ] , int target) Where , S = startindex E = endindex It is used for copying String characters to an array of chars. Ex : StringBuffer sb = new StringBuffer (“Java Program”); Char[ ] dst = new char[ ] {‘s’ , ‘t’ , ‘r’ , ‘i’ , ‘n’ , ‘g’ , ‘B’ , ‘u’ , ‘f’ , ‘f’ , ‘e’ , ‘r’ }; Sb.getchars(5,12,dst,2); System.out.println(dst); //stProgramer
- 9. ExampleofmethodStringBufferclass • StringBuffer sb = new StringBuffer (“VIE”); sb.SetLength (2); //VI • char c = sb.charAt (1); System.out.println(c); // V • sb.SetcharAt ( 0 , ‘A’); System.out.println(sb.toString()); //AIE • String str = “college”; sb.append(str); System.out.println(sb.toString()); //VIE college • sb.insert (1 , “kotambi”); System.out.println(sb.toString()); //VkotambiIE
- 10. • sb.reverse (); System.out.println(sb.toString()); //EIV • StringBuffer sb = new StringBuffer (“hellobye”); sb.replace(5,7,”hi”); System.out.println(sb.toString()); // hellohibye
