} 

//o/p is:

Enter name:faizan

Enter age:18

You are elgible to vote: faizan

\\ public and static method:

public class fa{

    static void method(){

        System.out.println("faizan");

    }

    public void method1(){

        System.out.println("public method");

    }

    public static void main(String[]args){

        method();

        fa obj =new fa();

        obj.method1();

    }

}

//o/p is:

faizan

public method

//abstract method make two classes fa and second

//In fa class

abstract class fa{

     public String name="faizan";

     public int age =18;

     public int passed=2023;

     

     public abstract void study();

}

class first extends fa{

    public void study(){

        System.out.println("abstract method is giving inter data");

    }

}

// In second class

class second{

    public static void main(String args[]){

    first obj = new first();

    System.out.println("name:"+obj.name);

    System.out.println("age:"+obj.age);

    System.out.println("inter:"+obj.passed);

    obj.study();

    }

}

//o/p is:

name:faizan

age:18

inter:2023

abstract method is giving inter data
