Answer / anilkumar
"==" is used to evaluate whether tht two objects are of same type or not.
Eg: A a1=new A();
A a2=new A();
A a3=a1;
a1==a2 returns false, because a1 reference and a2 reference are not same.
a3==a1 returns true because a3 reference is pointing to a1.
"equals()" compares the contents of objects.
Eg:A a1=new A(10);
A a2=new A(10);
A a4=new A(20);
a1.equals(a2) returns true because both contents are same.
a1.equals(a4) returns false because their contents are different.

System.out.println(s1.equals(s2));
