String s=new String("hello"); when the above statement is executed a String object is created and s is pointing to that object.

s=new String("world"); Now a new String object is created whose value is "world" and s is now pointing to the new object whose value is "world" .

So,now no reference is pointing to "hello" object but the object is not removed. And when u say System.out.println(s), it indirectly mean as System.out.println(s.toString());
