Q) Write a program for Equality?

A)

//Equality.java

class A1

{

       int a;

       int b;

       A1 (int a, int b)

       {

              this.a=a;

              this.b=b;

       }

       boolean equals(A1 r)

       {

              boolean flag = false;

              if(this.a == r.a && this.b == r.b)

                     flag = true;

              return true;

       }// overriding equals method to make the objects.equals if their state is the same.

}

class equality {

       public static void main(String[] args) {

              A1 a1 = new A1(10,2);

              A1 a2= new A1(10,2);

              System.out.println(a1.hashCode());

              System.out.println(a2.hashCode());

              if(a1.equals(a2))

                     System.out.println("both object are equal");

              else

                     System.out.println("not equal");

       }

}

Output:
33311724

14452073

both object are equal
