Java数组拷贝

使用Arrays.copyOf()方法拷贝数组元素到另一个数组中，不是拷贝的地址，而是值

package com.Project_03;import java.util.Arrays;public class StateMain {public static void main(String[] args){// TODO Auto-generated method stubSystem.out.println("num1拷贝之前：");int[]num1=new int[2];num1[0]=1;num1[1]=2;for (int i : num1) {System.out.println("num1:"+i);}//拷贝int [] num2=Arrays.copyOf(num1, num1.length);System.out.println("先拷贝后num1到num2，修改num1索引1的值：");num1[1]=21222;for (int i : num2) {System.out.println("num2:"+i);}System.out.println("修改num1索引1的值后打印");for (int i : num1) {System.out.println("num1:"+i);}}}
