180度旋转半金字塔（JAVA中的模式问题）

Question

我实际上是在打印这个图案：https://imgur.com/a/ObixO5I

import java.util.*;

public class ques5 {
    public static void main(String[] args) {
        try (Scanner sc = new Scanner(System.in)) {
            int n = 4;
            // outer loop
            for (int i = 1; i <= n; i++) {
                // inner loop
                for (int j = 1; j <= n - i; j++) {
                    System.out.print(" ");
                }
                for (int k = 1; k <= i; k++) {
                    System.out.print("*");
                }
            }
        }
    }

}

我得到的输出是：* ** *******

Answer 1

试试这个

import java.util.*;

public class ques5 {
    public static void main(String[] args) {
        try (Scanner sc = new Scanner(System.in)) {
            int n = 4,m=1;
            // outer loop
            for (int i = n; i >=1; i--) {
                // inner loop
                for (int j = 1; j <= i - 1; j++) {
                    System.out.print(" ");
                }
                for (int k = 1; k <= m; k++) {
                    System.out.print("*");
                }
                System.out.print("\n");
                m++;
            }
        }
    }

}

Answer 2

在第二个内循环结束时添加System.out.println（）。
