Note that the equals() and hashcode aggrement is not strictly required, but it is relied upon by the numerous JDK classes that use an internal Hashtable, eg the various java.util.Hashxxx classes.
Question 2 : If the answer is because they both have same hash code,only then equals will be called, then why its not called for below code. sset.add (obj1); sset.add (obj4); sset.add (obj2); sset.add (obj4); output is : in hash code value is 98 in hash code value is 97 in hash code value is 99 in hash code value is 97.
