I am starting to learn java, bur can't get this to work.

Make a small change in the program, so the output becomes

public class UsingClassConstant public static tinal int LINES 3 public static void main (String[] args) for (int i = 1; i = LINES ; i++) for (int j 1; j = LINES ; j++) System.out.print ("+-") System.out.println("+")
