Could any one please tell me the meaning of "++" with array in the following code in Java:

   int [ ] arr = new int[ 4 ];
   for(int i = 0; i < arr.length; i++){
        arr[ i ] = i + 1;
       System.out.println(arr[ i ]++);
   }

what is arr[ i ]++ meaning in above code, and why we can't do like:

arr[ i ]++ = i + 1;
