hashcode() and equals() method [duplicate]

Answer 1

Multiple objects having same hash are stored as LinkedList and new elements are added at HEAD. So in your case since all have the same hash, LinkedList is in following order:

Martin->Peter->Alex.

When you add another "Alex" the list is traversed from HEAD.

To test:

public boolean equals(Object obj)
   {
       Employee e1=(Employee)obj;
       System.out.println(this.name +  "'s equals has just been called against " + e1.name );
       return ((name.equals(e1.name)) && (empid==e1.empid));
   }
