Command-line arguments are given after the name of the program in command-line shell of Operating Systems.
To pass command line arguments, we typically define main() with two arguments : first argument is the number of command line arguments and second is list of command-line arguments.
While doing programming in any programming language, you need to use various variables to store various information. Variables are nothing but reserved memory locations to store values. This means that when you create a variable you reserve some space in memory.
You may like to store information of various data types like character, wide character, integer, floating point, double floating point, boolean etc. Based on the data type of a variable, the operating system allocates memory and decides what can be stored in the reserved memory.

Software testing is the process of executing software in a controlled manner. It is often used in association with the terms verification and validation. Verification is the checking or testing of items, including software, for conformance and consistency with an associated specification. Software testing is just one kind of verification, which also uses techniques such as reviews, analysis, inspections and walk throughs. Validation is the process of checking that what has been specified is what the user actually wanted.

Interview questions and answers for quality assuranceGaruda Trainings
Future of Software Testing is always good... as long as developers are developing projects we will be testing them and even when they stops developing then also we will test the enhancements and maintenance etc... Testing will always be needed
Customer will never accept the product Without complete testing .Scope of testing is always good as it gives everyone a confidence of the work we all are doing...Its always good to add more processes while doing testing so that one should not think that testing is a boring and easy job....Process is very imp. for testing.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Fundamental Classes
Overview of java.lang package Object
The package java.lang contains classes and interfaces that are essential to the Java
language. These include:
•
Object Class
•
Math Class
•
The wrapper classes
•
String
•
StringBuffer
•
StringTokenizer
java.lang (non-objectives)
Cloneable : A class implements the Cloneable interface to indicate to the
clone method in class Object that it is legal for that method to make a field-forfield copy of instances of that class.
SecurityManager : The security manager is an abstract class that allows
applications to implement a security policy.
Exceptions : The class Exception and its subclasses are a form of Throwable
that indicates conditions that a reasonable application might want to catch.
Errors : An Error is a subclass of Throwable that indicates serious problems
that a reasonable application should not try to catch. Most such errors are
abnormal conditions.
ClassLoader : The class ClassLoader is an abstract class. Applications
implement subclasses of ClassLoader in order to extend the manner in which the
Java Virtual Machine dynamically loads classes.

java.lang.Object
Class Object is the root of the class hierarchy. Every class has Object as a
superclass. All objects, including arrays, implement the methods of this class.
public boolean equals( Object object )
a) should be overrided
b) provides “deep” comparison
c) not the same as ==!
•
•
== checks to see if the two objects are actually the same object
equals() compares the relevant instance variables of the two
objects
public String toString()
a)should be overrided
b) returns a textual representation of the object
c) useful for debugging
java.lang.Math :
The class Math contains methods for performing basic numeric operations
such as the elementary exponential, logarithm, square root, and trigonometric functions.
class is final
constructor is private
methods are static
public static final double E
•
as close as Java can get to e, the base of natural logarithms
public static final double PI
•
as close as Java can get to pi, the ratio of the circumference of a circle to
its diameter

mathematical integer
• double x = Math.ceil( 423.3267 ); x == 424.0;
double floor( double d )
• returns the largest integer that is not greater than d, and equal to a
mathematical integer
• double x = Math.floor( 423.3267 ); x == 423.0;
double random()
• returns a random number between 0.0 and 1.0
• java.util.Random has more functionality
double sin( double d )
• returns the sine of d
double cos( double d )
• returns the cosine of d
double tan( double d )
• returns the tangent of d
double sqrt( double d )
• returns the square root of d
java.lang Wrapper Classes
Wrapper class wraps (encloses) around a data type and gives it an object appearance.
Wherever, the data type is required as an object, this object can be used.
Wrapper classes include methods to unwrap the object and give back the
data type. It can be compared with a chocolate. The manufacturer wraps the chocolate
with some foil or paper to prevent from pollution. The user takes the chocolate, removes
and throws the wrapper and eats it.

encapsulates a single, immutable value
all wrapper classes can be constructed by passing the value to be wrapper to the
constructor
• double d = 453.2344;
• Double myDouble = new Double( d );
can also pass Strings that represent the value to be wrapped (doesn’t work for
Character)
• Short myShort = new Short( “2453” );
• throws NumberFormatException
the values can be extracted by calling XXXvalue() where XXX is the name of the
primitive type.
wrapper classes useful for classes such as Vector, which only operates on
Objects
java.lang.String
The String class represents character strings. All string literals in Java programs, such
as "abc", are implemented as instances of this class.
Strings are constant; their values cannot be changed after they are
created. String buffers support mutable strings. Because String objects are immutable
they can be shared.
uses 16-bit Unicode characters
represents an immutable string
Java programs have a pool of literals
• when a String literal is created, it is created in the pool
• if the value already exists, then the existing instance of String is
used
• both == and equals() work

Difference between equals() and ==
Example:1
String s1 = “test”;
String s2 = “test”;
s1 == s2; // returns true
s1.equals( s2 ); // returns true
Example:2
String s3 = “abc”;
String s4 = new String( s3 );
s3 == s4; // returns false
s3.equals( s4 ); // returns true

java.lang.StringBuffer
A thread-safe, mutable sequence of characters. String Buffer represents a String which
can be modified and has a capacity which can grow dynamically. String buffers are safe
for use by multiple threads.
The methods are synchronized where necessary so that all the operations
on any particular instance behave as if they occur in some serial order that is consistent
with the order of the method calls made by each of the individual threads involved.

StringTokenizer
The string tokenizer class allows an application to break a string into tokens. The
tokenization method is much simpler than the one used by the StreamTokenizer class.
The StringTokenizer methods do not distinguish among identifiers, numbers, and
quoted strings, nor do they recognize and skip comments.
The set of delimiters (the characters that separate tokens) may be specified
either at creation time or on a per-token basis.
An instance of StringTokenizer behaves in one of two ways, depending on
whether it was created with the returnTokens flag having the value true or false:
If the flag is false, delimiter characters serve to separate tokens. A token is
a maximal sequence of consecutive characters that are not delimiters.
If the flag is true, delimiter characters are considered to be tokens. A token
is either one delimiter character, or a maximal sequence of consecutive
characters that are not delimiters.
