assertNotSame pRmeters

[sameera liyanage]

this example i got from internet.
it shows assertNotSame method takes one time two parameters and one time three parameters.
why is that

import junit.framework.*;

public class AssertNotSameExample extends TestCase{

  public void test(){
    int expected = 2;
    int actual = 2;
    try{
      assertNotSame(expected, actual);
    }catch(AssertionError exception){ }
  }

  public void test01(){
    int expected = 2;
    int actual = 4;
    try{
      assertNotSame("not same", expected, actual);
    }catch(AssertionError exception){ }
  }
}
