swapping of objects in java [duplicate]

Answer 1

We can swap objects. It's so simple.Just have to use one dummy object to swap two objects.

Example is given below:

    Employee e1=new Employee();
    Employee e2=new Employee();
    e1.setName("e1");
    e2.setName("e2");   
    System.out.println(e1);
    System.out.println(e2);
    Employee temp= new Employee();
    temp=e1;
    e1=e2;
    e2=temp;
