String和List相互转换

String转List

先将string转成数组再转成list

String str="a,b"; 

String[] strs=str.split(",");

List list=Arrays.asList(strs);

List转String

直接调用 方法

StringUtils.join(list,separator)

例如：

package com.data.handle;

import java.util.Arrays;
import java.util.List;

import org.apache.commons.lang.StringUtils;

public class test3 {
	public static void main(String args[]) {
		String name = "a,b,c";
		String[] names = name.split(",");
		List nameList = Arrays.asList(names);
		String str = StringUtils.join(nameList, ",");
		System.out.println(nameList);

		System.out.println(str);
	}
}
