This document discusses various Java concepts like object-oriented programming, compilation, the main method signature, command line arguments, byte code checking, type casting, and input/output in Java using classes like DataInputStream and Scanner. It provides code examples for accepting user input using these classes and parsing the input into different data types like integer and float. It also compares DataInputStream and Scanner, noting that Scanner avoids the need to manually convert input types.
oops concept in java | object oriented programming in javaCPD INDIA
object oriented programming is a key concept for the development of application in windows as well as web based application environment. oops concept maps real world through its concept of classes, objects, inheritance, polymorphism which help in making a robust application.
Inheritance in java is a mechanism in which one object acquires all the properties and behaviors of parent object. The idea behind inheritance in java is that you can create new classes that are built upon existing classes.
In DBMS (DataBase Management System), the relation algebra is important term to further understand the queries in SQL (Structured Query Language) database system. In it just give up the overview of operators in DBMS two of one method relational algebra used and another name is relational calculus.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

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.

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.
2. what is the meaning of true object
oriented
If we want to do anything in java must be
within a class
3. what is the meaning of
program compilation
Compilation means to convert your actual
programme or source code in to the
machine code or byte code
Machine code machine independent
Run or execute on any operating system
or plat forms is called as platform
independent this is a feature of java
4. what is public static void
main(String x[])
This is the main function of java same like
as main function in c
Static content can share all members in
application so main is available in whole
application
Static content load in memory very first
when program run. for program execution
main method must be load in memory so
main is static
5. what is String x[]
This is a command line argument in java
If we pass the any parameter to main
function is called as command line
argument
what is the use of command line argument in
java
To provide the run time input
7. How to cross check byte code
created or not
After the program compile java create
the one new file automatically is called
as .class file and in this file contain byte
code
Use the command line argument
8. If you want provide the input at run
time
Use the command line argument
Or
Java provide the some inbuilt classes for
input. Command line argument is infinite
string array means we can pass the n
number of input through the command line
argument but the first input start with
zero index(basic array rule)
9. type casting
how to perform the type casting or
type conversion in java
for that java provide some inbuilt classes
for conversion is called as wrapper classes
syntax -->
integervariable=Integer.parseInt(value for conversion|);
e.g. a=Integer.parseInt(x[0]);
10. Integer is a class in java and parseInt() is
the static method of Integer class this
method is used to convert the any value.
floatvriable=Float.parseFloat(value);
or
Float.valueOf(value).floatValue();
11. public class FirstBatch{
public static void main(String x[])
{ int a,b,c;
a=Integer.parseInt(x[0]);
b=Integer.parseInt(x[1]);
c=a+b;
System.out.println("Addition is "+c);
}
}
12. DataInputStream
This class is used to accept the input
from keyboard same like as scanf() in c
this class is a member of java.io package
To add follow some step’s
Add java.io. pacakge in programme
package is a collection of classes same like
as header file in c
header file is a collection of functions in c
13. import packagename;
e.g. import java.io.*; -->this statement
allow us to use all classes present in
java.io.
import java.io.DataInputStream;-->we can
use only one class in program from java.io
package
import is the keyword in java which is used
to add the package in program
14. create the object of DataInputStream
class
if we want to use the class and its
member any where for that we need to
object
Synatx
DataInputStream objectname=new DataInputStream(System.in);
16. use its readLine() method for input
readLine() is the method of
DataInputStream class which is used to
accept the input from keyboard
Use of readLine() method
objectofdatainputstream.readLine()
17. //P1 import java.io.*;
public class DataFirst
{
public static void main(String x[])throws
Exception
{
DataInputStream xyz=new DataInputStream(System.in);
int num,sq;
System.out.println("Enter the number");
19. //P2
import java.io.*;
public class Student
{
public static void main(String x[])throws Exception
{
DataInputStream input=new DataInputStream(System.in);
int number;
String name;
float marks;
System.out.println("enter the name of student");
name=input.readLine();
System.out.println("Enter the id of student");
number=Integer.parseInt(input.readLine());
System.out.println("Enter the marks of student");
}
21. Problem with readLine() method
Need to convert for every input other than
string for that java provide the another
optional class for input to us Scanner .
22. Scanner is a class same like as
DataInputStram Scanner is a member of
java.util package
add the util package in programme
import java.util.*;
create the object of Scanner class
Scanner object=new Scanner(System.in);
e.g Scanner input=new Scanner(System.in);
Use its following method for input
23. nextInt() --> for integer input
nextFloat() ---> for float input
nextDouble() --> for double input
nextByte() --> for byte input
nextLine() ----> for string input
nextShort() -->short integer input
nextLong() ---> for long integer input
24. import java.util.*;
public class ScannerApp
{
public static void main(String x[])
{
Scanner xyz=new Scanner(System.in);
int id;
float marks;
String name;
System.out.println("Enter the name ");
name=xyz.nextLine();
System.out.println("enter the id ");
id=xyz.nextInt();
System.out.println("enter the marks ");
