3) Run this code as (java CreateJar).

After this you have got two class files (1) AddData.class and (2) CreateJar.class.

4) Create A Menifest.txt file, In this file write Main class name.

Main-Class: CreateJar

5) Create A folder as createJar name, Then past all three files.
AddData.class, CreateJar.class, Menifest.txt

After complete these process, open Command prmpt and type

jar -cfmv CreateJar.jar Menifest.txt *

Commands for jar:-

For Creating Jar:
jar -cfmv CreateJar.jar Menifest.txt *

For Xtracting Jar:
jar -xfv CreateJar.jar

For executing Jar:
java -jar CreateJar.jar

/*compile this java code and create your own jar */

import java.util.Scanner;

class CreateJar {
    public static void main(String args[]){
    Scanner scan = new Scanner(System.in);


    System.out.println("enter value 1 :");
    int a = scan.nextInt();

    System.out.println("enter value 2 :");
    int b = scan.nextInt();
       AddData ad = new AddData(a,b);
       ad.adddata();
    }
}

class AddData{
    int a,b;
    public AddData(int a, int b){
        setA(a);
        setB(b);
    }

public int getA() {
    return a;
}

public void setA(int a) {
    this.a = a;
}

public int getB() {
    return b;
}

public void setB(int b) {
    this.b = b;
}

public void adddata(){

    int c = getA()+getB();

    System.out.println("Addition is : "+c);

}
