Java 实例 – 打印倒立的三角形
Java 实例打印倒立的三角形。
实例
public class InvertedTriangle { public static void main(String[] args) { //打印倒立的三角形 for (int m = 1; m <= 4; m++) { //打印空格 for (int n = 0; n <= m; n++) { System.out.print(" "); } //打印* for (int x = 1; x <= 7 -2 * (m - 1); x++) { System.out.print("*"); } System.out.println(); } } }
输出结果：
