for循环的一个复制算法(Java)

public class ForDemo0 {
    public static void main(String[] args) {
        int[] num={10,20,30,40,50};  //定义一个数组
        for (int i = 0; i < 5; i++) {
            System.out.println(num[i]);
            
        }
        System.out.println("======================================= ");

        //遍历数组元素
        //将num数组每一项复制给x
        for(int x:num)
        {
            System.out.println(x);
        }
    }

}
