java List与array互相转换

叔叔不说 不解释 不约，直接上代码

package cn.kge.one;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

public class Demo1 {
    public static void main(String[] args) {
        List<String> list = new ArrayList<String>();
        list.add("a");
        list.add("b");
        list.add("c");
        list.add("d");
        list.add("e");
        String[] strArray = list.toArray(new String[list.size()]);
        for(String str:strArray){
            System.out.println(str);
        }
        System.out.println("-------------------优美的分割线------------------");
        String[] strings = {"1","2","3","4"};  
        List<String> content = Arrays.asList(strings);

        for(String str:content){
            System.out.println(str);
        }
    }
}
