JAVA 数组的复制

实现代码

import java.util.Scanner;
public class Test8 {
    public static void main(String[] args) {
        int[] arr1 = new int[3];
        Scanner sc = new Scanner(System.in);
        for(int i = 0 ; i< arr1.length ; i++){
            arr1[i] = sc.nextInt();
        }
        //创建数组arr2
        int[] arr2 = new int[3];
        //使用for循环将arr1的数据复制给arr2
        int temp = 0;
        for(int j = 0;j
            temp = arr1[j];
            arr2[j] = temp;
        //输出arr2
        System.out.println(arr2[j]);
        }
    }
}
