How to escape + character in java?

Question

How to escape + character while using split function call in java?

split declaration

String[] split(String regularExpression)

thats what i did

services.split("+"); //says dongling metacharacter

services.split("\+"); //illegal escape character in string literal

But it allows to do something like this

String regExpr="+";

Answer 1

Since the + is a regex meta-character (denoting an occurrence of 1 or more times), you will have to escape it with \ (which also has to be escaped because it's a meta-character that's being used when describing the tab character, the new line character(s) \r\n and others), so you have to do:

services.split("\\+");
