How to test ArrayIndexOutOfBoundsException?

Question

I have never tested with JUnit, not sure what I have to do in this case

@Test(expected = ArrayIndexOutOfBoundsException.class)
public void throwsArrayIndexException() {
    ...
}

I just have to test that if args[0]==0 in main method, ArrayIndexOutOfBoundsException is expected, I tried with if(args[0]==0){throw new ArrayIndexOutOfBoundException} but didn't work.. I appreciate your help! Thanks in advance!

@Test(expected = ArrayIndexOutOfBoundsException.class) 
public void throwsArrayIndexException() {
  int [] array = new int[] {};
  int num = array[1];
}
