Java version

String s = "MAT:TO:My address email;SUB:My title;BODY:My content;;";
String[] arrayString = s.split(";");

String email = arrayString[0];
String title = arrayString[1];
String body = arrayString[2];

email= email.substring(email.indexOf("MAT:TO:") + 7, email.length());
title= title.substring(title.indexOf("SUB:") + 4, title.length());
body= body.substring(body.indexOf("BODY:") + 5, body.length());

Especially Android official is used kotlin version:

val s = "MAT:TO:My address email;SUB:My title;BODY:My content;;"
val arrayString = s.split(";").toTypedArray()

var email = arrayString[0]
var title = arrayString[1]
var body = arrayString[2]

email = email.substring(email.indexOf("MAT:TO:") + 7, email.length)
title = title.substring(title.indexOf("SUB:") + 4, title.length)
body = body.substring(body.indexOf("BODY:") + 5, body.length)

Please, what is work of +7 in the first line email = email.substring(email.indexOf("MAT:TO:") + 7, email.length) — chisom emmanuel, May 15 '22 at 21:38

Try using the split() method.

If you want to split by ";"

String[] arrayString = string.split(";");

In your case you would get

["MAT:TO:My address email", "SUB:My title", "BODY:My content"]

and then split by ":" or the other way around, whichever better suits you.

String email = arrayString[0].split(":")[2];
String title = arrayString[1].split(":")[1];
String body = arrayString[2].split(":")[1];

This is a bad way to do it, not very safe.

Or you could use string.substring(int startIndex, int endIndex).
