增强For循环 为后边数组做准备

 

package struct;

public class ForDemo05 {
    public static void main(String[] args) {
        //定义：数据类型+变量名
        int[] numbers = {10,20,30,40,50};//定义一个数组
        for (int i=0;i<5;i++){
            System.out.println(numbers[i]);
        }
        System.out.println("==============================================================");
        //遍历数组的元素 相当于上边的简化
       
        for (int x:numbers){
            System.out.println(x);
        }
    }
}
