Java căn bản - Chapter8
This chapter discusses exceptions and assertions in Java. The key points are:
1. Exceptions represent error conditions and allow for graceful handling of problems rather than program crashes. Exceptions can be caught and handled using try-catch blocks.
2. Checked exceptions must be caught or propagated using throws, while unchecked exceptions are for runtime errors and catching is optional.
3. Assertions use the assert statement to check for expected conditions and throw errors if false, helping find bugs. Assertions must be enabled during compilation and execution.
Flow of control C ++ By TANUJ
This document provides an overview of different types of statements and flow control constructs in C++ programming. It discusses sequential, selection, and iteration statements. Selection statements covered include if, if-else, switch, and ternary operator. Iteration statements discussed are for, while, do-while, and nested loops. Jump statements like break, continue, goto, and exit function are also summarized. Examples are provided for most constructs to illustrate their usage.
Control statements
Control statements regulate the order of execution of statements in a program. There are three main types of control statements: sequence statements, selection statements (if/else, switch), and looping/iteration statements (for, while, do-while). Sequence statements execute statements sequentially from top to bottom. Selection statements execute certain statements conditionally based on if/else or switch conditions. Looping statements repeatedly execute a block of code for a specified number of times or as long as a condition is true. Other statements like break, continue, and return can change the normal flow of control.

This document provides an overview of exceptions and exception handling in C++. It discusses how exceptions provide an alternative way to handle error conditions compared to traditional error handling methods. Exceptions allow errors to be handled in a centralized location rather than after every function call. The document explains how to throw exceptions using the throw keyword, catch exceptions using try/catch blocks, and specify which exceptions a function can throw. It also discusses efficiency concerns, throwing exceptions in constructors and destructors, and resource management related to exceptions.
Control Structures
There are three main types of control structures in computer programming: sequential logic, selection logic, and iteration logic. Sequential logic executes code line-by-line. Selection logic (e.g. if/else statements) allows executing code conditionally. Iteration logic (e.g. for loops) repeats code execution in loops. The document provides examples of if/else, nested if, switch statements, and the conditional operator for implementing various control structures in C programming.

Do you need commercial auto insurance By Floyd Arthur (PPT)
Commercial auto insurance covers vehicles used for business purposes like transporting goods, people, or equipment. It provides similar coverage to personal auto insurance but with higher liability limits and additional optional coverage. The cost of commercial auto insurance depends on factors like the number of vehicles and employees, their driving histories, how and where the vehicles are used, and what is transported. Rates can range from $1,200-$2,400 for passenger vehicles, $5,000-$10,000 for taxis/livery, and over $2,500 for tractor-trailers depending on these risk factors.

Here is a Java program that takes integer input from the user between 0-100 and prints the number in English:
import java.util.Scanner;
public class NumberToWords {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.print("Enter a number between 0-100: ");
int num = sc.nextInt();
if(num < 0 || num > 100) {
System.out.println("Number is out of range!");
return;
}
String word = numberToWord(num);
System.out.println(word);
}
public static String numberToWord(int number)
Ch3- Java Script.pdf
This document discusses JavaScript as a scripting language that allows for dynamic web pages. It covers running JavaScript code using <script> tags, working with variables and data types, operators and expressions, conditional statements like if/else and switch, and loops. Key points include JavaScript being interpreted rather than compiled, adding JavaScript via embedded, inline, or external code, and using variables, comments, arithmetic, comparison, assignment and logical operators.
slides03.ppt
The document discusses program statements in Java. It covers:
- The four basic activities of program development: establishing requirements, creating a design, implementing code, and testing.
- Conditional statements like if, if-else, and switch that allow modifying the flow of control through a method.
- Logical operators like && and || that can be used to form complex boolean expressions for conditionals.
Final requirement
The document discusses switch case statements in programming. It provides details on the basic format and usage of switch case statements, including that they allow a variable to be tested for equality against multiple values through different cases. The document also notes some key rules for switch cases, such as requiring a break statement at the end of each case and that case values must be integer or character constants. It provides examples of switch case statements and discusses how they can provide a cleaner alternative to long if-else statements.
Loops and conditional statements
The document discusses different types of loops and conditional statements in programming languages. It explains the if, if-else, and switch conditional statements, providing examples of each. It also covers different types of loops - while, do-while, for, and nested loops. Examples are given to illustrate the syntax and usage of each loop and conditional statement.

Chapter 2.2 data structures
The document discusses data structures and algorithms. It defines arrays as a series of objects of the same size and type, where each object is an element that can be accessed via an index. Algorithms are described as finite sequences of instructions to solve problems, with analysis of algorithms determining the resources like time and storage required.
Chapter 1 introduction to java technology
This document provides an introduction to Java programming, covering topics such as its origins, key features like being simple, object-oriented, distributed, interpreted, robust, secure, architecture-neutral, portable, high-performance, and dynamic. It also discusses how to program in Java, including the Java platform which consists of the Java Virtual Machine and Java Application Programming Interface, and different types of programs like applets, applications, and servlets.
Chapter3 basic java data types and declarations
The document discusses basic Java declarations including constants, variables, type casting, and strings. It provides examples of declaring and assigning constants and variables in Java. It also describes common string methods like length(), equals(), toUpperCase(), and substring() and provides examples of how to use them.
Chapter2 java oop
Object-oriented programming uses objects that contain data and methods to design applications. Key concepts include information hiding, encapsulation, inheritance, polymorphism, and modularity. Many modern programming languages now support OOP. Objects are instances of classes that define their characteristics and behaviors. Subclasses inherit attributes and behaviors from parent classes and can introduce their own. Polymorphism allows methods to behave differently depending on an object's type.
Exercises for ja se
The document provides information on Java methods and classes for input/output operations. It explains that the main method is called to start a Java application and must be public and static. It also describes the BufferedReader and InputStreamReader classes which can be used to read text from character streams and files in an efficient buffered manner.
Chapter 5 declaring classes & oop
This chapter discusses object-oriented programming concepts like encapsulation, inheritance, polymorphism, abstract classes, and exception handling in Java. Encapsulation involves making data fields private and controlling access via public methods. Inheritance allows classes to extend existing classes and polymorphism means that subclasses can override methods of the parent class. Abstract classes cannot be instantiated and serve as a base for subclasses, while exceptions are used to handle errors.
