Give Me A Instance Example In Java Program. Can You Help?

Well I am not clear with your Question

I suppose you want to know the instance of a class in java. I am guessing so...


public class InstanceDemo {

    int no1;    //class data member of type int
    int no2;    //also called as 'field' of type int in java
    
    String tmp; //class data memberof type String

    //Constructor
    public InstanceDemo(int no1, int no2, String tmp) {
        this.no1 = no1;
        this.no2 = no2;
        this.tmp = tmp;
    }
    
    public void display() {
        System.out.printl name : " + this);
        System.out.printl name : " + this.getClass());
        
        System.out.printl />        
        System.out.printl : " + no1 + " *** and *** " + "no2 : "+ no2);
                
        // this reference can also be used for a clear idea
        System.out.printl : " + this.tmp);
        System.out.printl />    }
    
    public static void main(String[] args) {
        //creating object
        //here instanceDemo is an Instance of class InstanceDemo
        //instance simply means Object of a class
               
        InstanceDemo instanceDemo1 = new InstanceDemo(10, 20, "Hello");
        InstanceDemo instanceDemo2 = new InstanceDemo(20, 30, "World!");
        
        //we can create as many instance's as we wish
        //but always remember each instance will have it's own copy of fields
        instanceDemo1.display();
        instanceDemo2.display();
    }   
}
