java202302java学习笔记第九天-数组的遍历和三道综合学习5代码遍历

public class Demo04 {
    public static void main(String[] args) {
        //定义数组
        int[] arr = {1,2,3,4,5};
        System.out.println(arr[0]);
        System.out.println(arr[1]);
        System.out.println(arr[2]);
        System.out.println(arr[3]);
        System.out.println(arr[4]);
        //数组遍历
        for(int i=0;i<=arr.length;i++){
            System.out.println(i);
        }
        for (int i = 0; i < arr.length; i++) {
        }
    }
