Answer / rajshekaran pillai
As the JVM assigns the hashcode to an object value and not
the reference the hashcode for the same object will be same.
the equals() method of the object class uses this hashcode
to evaluate if the objects have same value. therefore
Object o1 = new String("ABC");
Object o2 = "ABC";
/**
* will have the same hashcode
* therefore when we do..
*/
if(o1 == o2){
System.out.println("The object reference is same");
}else if(o1.equals(o2)){
System.out.println("The object has same value");
}
/**
* The output is
* The object has same value
*/
