java - Android将字符串分割成2个字符串

Question

我有

字符串 s = "hello=goodmorning,2,1"

有人可以帮我编写有关如何拆分 s 使其等于以下内容的代码吗:

String s2 = "hello"
String s3 = "goodmorning"
string s4 = "2,1"

Answer 1

String s = "hello=goodmorning,2,1"

String[] str = s.split("=");  //now str[0] is "hello" and str[1] is "goodmorning,2,1"

String str1 = str[0];  //hello

String[] str2 = str[1].split(",");  //now str2[0] is "goodmorning" and str2[1] is "2,1"

String str3 = str2[0];  //goodmorning
String str4 = str2[1];  //2,1

输出:

str1 = hello;
str3 = goodmorning;
str4 = 2,1;
