打印三角形(java的for循环)

public class test {
    public static void main(String[] args){
//输出n行的三角形
        int n= 25;
        for (int j = 0; j < n; j++) {
            for (int i = j; i < n; i++) {
                System.out.print(" ");
            }
            for (int i =n- j; i < n; i++) {
                System.out.print("*");
            }
            for (int i = n-j;i<=n;i++){
                System.out.print("1");
            }
            System.out.print("\n");
        }
    }
