List与数组之间的互相转换
package com.test;import java.util.ArrayList;
import java.util.List;
public class Test {
public static void main(String[] arg){
String[] str=new String[]{"A","B","C","D","E"};
List<String> alist= java.util.Arrays.asList(str);
for(int i=0;i<alist.size();i++){
System.out.println("====="+alist.get(i)+"=====");
}
String[] str2=alist.toArray(new String);
for(int i=0;i<str2.length;i++){
System.out.println("-----"+str2+"-----");
}
}
}
运行结果
=====A=====
=====B=====
=====C=====
=====D=====
=====E=====
-----A-----
-----B-----
