Why should override hashcode method while overriding equals method

Why equals method says that two instances are different although they are instances of same class and have same age? Reason : While invoking equals method first hashcode() method is executed . If hashcode() method returns different hashcode value for instances being compared equals() method is not called. Different hashcode declares that instances are different and no further comparison takes place. So Is hashcode values for above tow instances are different ?
