java declaration not clear

[nilotpal sarkar]

I got a declaration like this.

Object obj=constructor.newInstance(new Object[] {"abc"});
//constructor is a object of Constructor class(using reflection)

i am not clear with the declarartion like this.can some1 explain what is in the brace{"abc"}, as well as the complete declaration in detail.
thanx in advance.

It's just a short cut of

Object[] objectArray = new Object[] {"abc"};
Object obj=constructor.newInstance(objectArray);
 

Now,

Object[] objectArray = new Object[] {"abc"};
 

Is itself a shortcut of creating a new array and populating it at the same time.
e.g if I wanted an array with the integers 0, 3, 5, 1, 9 I could do it as follows

        int[] rzero = new int[5];
        rzero[0] = 0;
        rzero[1] = 3;
        rzero[2] = 5;
        rzero[3] = 1;
        rzero[4] = 9;
        rzero[5] = 8;
 

Or the shortcut

 int[] rzero = new int[]{0,3,5,1,9,8};
