用for循环打印三角形

public class TestDemo01 {
    //打印三角形
    public static void main(String[] args) {
        for (int i = 1; i <= 8; i++) {
            for (int j = 8; j >= i; j--) {
                System.out.print(" ");
            }
            for (int j = 1; j <= i; j++){
                System.out.print("*");
            }
            for (int j = 1; j <i; j++){
                System.out.print("*");
            }
            System.out.println();
        }
    }
}
