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);
        }
	}
}
