Java split method is not working properly?

Question

This is my piece of code I want to split the string with $ symbol but the string doesn't getting spitted.

Here is my code:

   String str="first$third$nine%seventh";
   String s[]=str.split("$");
   System.out.println(s[0]);

The output is the whole string:

first$third$nine%seventh

Answer 1

This is a very common thing in string class. Ans this has been already asked and answers are available in stackoverflow.

You should escape the regular expression symbol in split method. There are so many characters like $,?,*,^,+ which should be escaped while using as a parameter in split method.

Answer 2

split takes a regular expression as an argument. $ is a magic character in regex.

If you escape it with backslashes, it will be used as a normal character instead of a special regex character.

String s[]=str.split("\\$");
