关于java数组复制问题！

[tonny1900]

我是java初学者，请各位大神多多指教！

import java.util.Arrays;

public class Lianxi {
public static void main(String[]args){
String arr1[]=new String[]{"ad","bv","ce","da"};
String arr2[]=new String[]{"ac","bb","se","ha"};
String arr2[]=Arrays.copyOfRange(arr1,0,3); //能否将数组arr1中的两个元素直接替换到arr2中去形成新的arr2数组呢？
for(String i:arr1){
System.out.print("\t"+i);
}
System.out.println();
for(String i:arr2){
System.out.print("\t"+i);
}
System.out.println();
}
}

arr2[1] = arr1[1]; arr2[2] = arr1[2];

[疼碍]

组成新的数组为什么还要用arr2接收
