  public class HelloWorld {

          public static void main(String[] args) {

           System.out.println("打印直角三角形");

                   for (int i = 1;i<4;i++) {

                           for (int j = 1;j<i;j++) {System.out.print(" ");

                    }

                    for (int j = 1;j<=4-i;j++) {

                            System.out.print("*");

                     }

                     System.out.println();

                     }

           }

  }

  这样吗？
