Android将字符串拆分为2个字符串

Question

我有

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

有人可以帮助我解决如何将s拆分为以下内容的代码：

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;

Answer 2

 String s = "hello=goodmorning 2 1 3 4";
 String[] str = s.split(" "); 
 String str1 = str[0]; 
 String new1 =s.replace(str1,"");
 System.out.println(new1);

输出为2 1 3 4

Answer 3

在Kotlin中添加

var s = "hello=goodmorning,2,1"
var str = s.split("=")
