Java字符串分割到map_如何在Java中按空格分割字符串并以键值形式存储在map中？...

您可以尝试此解决方案

import java.util.ArrayList;

import java.util.Arrays;

import java.util.List;

public class SplitTest {

public static void main(String[] args) {

String str="Reference=R1,R2 GroupId=G01 Date=12/02/ 15:25 GroupId2=G02 Date=12/02/ 30:25 Date=12/02/ 30:25 Date=12/02/ 30:25 GroupId3=G03";

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

List asList = Arrays.asList(split);

List newList = new ArrayList<>();

for (int i = 0; i < asList.size();) {

if(asList.get(i).toString().startsWith("Date")){

String str1 = asList.get(i);

String str2 = asList.get(i+1);

newList.add(str1+" "+str2);

i=i+2;

}else{

newList.add(asList.get(i));

++i;

}

}

System.out.println(newList.toArray());

}

}

输出量

Reference=R1,R2

GroupId=G01

Date=12/02/ 15:25

GroupId2=G02

Date=12/02/ 30:25

Date=12/02/ 30:25

Date=12/02/ 30:25

GroupId3=G03
