Answer 1

The string you send as an argument to split() is interpreted as a regex ( documentation for split(String regex) ). You should add an escape character before the + sign:

String splits[] = org.split("\\+");

You might also find the Summary of regular-expression constructs worth reading :)

Answer 2

"+" is wild character for regular expression. So just do

String splits[] = org.split("\\\\+");

This will work

Answer 3

the expression "+" means one or many in java regular expression. split takes Regex as a argument hence the comparion given by you fails So use

String org = "abcd+xyz";
String splits[] = org.split(""\\+");

regards!!

Answer 4

尝试：

String splits[] = org.split("\\+");
