增强型for

public class forDeemo02 {
    public static void main(String[] args) {
        int [] numbers = {10,20,30,40,50};
        for (int x:numbers){
            System.out.print(x+"\t");
        }
        //等同于
        /*
         for (int i = 0; i < 5; i++) {
                      System.out.print(x+"\t");
                 }
        */
    }
}

利用for循环做金字塔

package com.caster.struct;

public class Deemo01 {
    public static void main(String[] args) {
        //打印三角形
        for (int i = 1; i <= 5; i++) {
            for (int j = 5; 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();
        }
    }
}
