如何将string转换成list

import java.util.Arrays; import java.util.List; public class test { public static void main(String[] args) { // 字符串转list String str = "aaa,bbb,ccc"; List lis = Arrays.asList(str.split(",")); for (String string : lis) { Syst...

将List集合转换成String的数组的方法如下: 输入代码: [java] view plain copy List list = new ArrayList(); list.add("a1"); list.add("a2"); String[] toBeStored = list.toArray(new String[list.size()]); for(String s : toBeStored) { S...

实体类型如果为数组的话,可以直接通过list的add方法进行添加转换,举例: List list = new ArrayList();//定义一个数组类型的list对象 String[] entity = new String[10];//创建一个要实体化的数组对象 entity[0] = "1232";//给数组赋值 list....

List存放的是多个string变量,所以转化的话一般是转换成string[]。转换过程就是一个一个赋值。方法如下: public string[] listConvertToArray(List strList) { string[] strArray = new string[strList.Count]; for (int i = 0; i < strList.Co...

具体点,是按条件分解字符串放到list里面吗? string ss=“asdfasdf,werwe,werwer”; Arrays.asList(ss.split(","));

List list = new ArrayList(); String[] strArr = new String[list.size()]; list.toArray(strArr);

List list = new ArrayList(); //list中添对象 list.add("a"); list.add("b"); list.add("c"); StringBuffer sb = new StringBuffer(); for(String s:list){ sb.append(s) } System.out.println(sb.toString());

public class Test { public static void main(String[] args){ List list = new ArrayList(); A a1 = new A("101","01","122222222","上海"); A a2 = new A("102","02","133333333","南京"); A a3 = new A("103","03","142333223","上海"); A a...

这样的我们只有自己写代码分割,首先我们提取[]里面的内容,然后使用,分割成数组,然后转在list 代码如下: String demo = "[a,b,c]"; String demosub = demo.substring(1,demo.length()-1); String demoArray[] = demosub.split(","); List de...

public String[] changeListToArrays(List list){ String args[] = new String[list.size()]; for(int i=0; i< list.isze(); i++){ args[i] = list.get(i); } return args; }
