    Red face array copy!!!

    ok so I am trying to learn about arrays, and I found thee on a book that you can use the arraycopy method to do it more simple
    so I did these code with the directions It is really not a big deal but I cannot figure out what is wrong I keep getting the same error that I need object, and I have arrays, but I found it under arrays topic. maybe is so dumb I am donīt see it. I would appreciate some help.
    the code is the following
     public class  ArrayCopy{
     
          public static void main(String[]args){
     
             int[]sourceArray={1,2,3,5,3,6};
     
             int[]targetArray= new int[6];
     
             System.arraycopy(sourceArray, 0, targetArray, 0);
     
          for( int i =0; i<targetArray.length; i++)
     
          System.out.println("Taget Array");
          System.out.println( targetArray[i] + " " );
     
          }}
