增强For循环

public class ForDemo05 {
    public static void main(String[] args) {
        int[] numbers = {10,20,30,40,50};//定义了一个数组


        for (int i = 0;i<5;i++){
            System.out.println(numbers[i]);
        }
        System.out.println("=============================");
        //便利数组的元素
        for (int x:numbers){
            System.out.println(x);
        }
    }
}
