package com.snape.java._5th.Test61;

public class ArrayCopy {
    public static void main(String[] args) {
        int[] arr1 = {1,2,3,4,5,6,7,8,9};
        int[] arr2 = new int[arr1.length];

        System.arraycopy(arr1,0,arr2,0,arr1.length);

        System.out.println("原数组：");
        arrayPrint(arr1);
        System.out.println("--------------------------");
        System.out.println("复制得到的数组：");
        arrayPrint(arr2);
    }

    //打印数组
    public static void arrayPrint(int[] arr){
        for(int i : arr){
