java案例代码4-数组的复制

看注释即可

package M1package;


public class arraycopy {

    public static void main(String[] args) {
        int[] arr1={11,22,33,44,55};
        int[] arr2=new int[arr1.length];

        copy(arr1,arr2);  //调用复制数组的函数

        printArray(arr1);  //调用打印数组的函数
        System.out.println();
        printArray(arr2);


    }


    //但因数组的函数
    public static void printArray(int[] arr){
        System.out.print("[");
        for (int i = 0; i < arr.length; i++) {
            System.out.print(i==arr.length-1?arr[i]:arr[i]+", ");


        }
        System.out.print("]");



    }

    public static void copy(int[] arr1,int[] arr2){

        for (int i = 0; i
