How to match a string's end using a regex pattern in Java?

Question

I want a regular expression pattern that will match with the end of a string.

I\'m implementing a stemming algorithm that will remove suffixes of a word.

E.g. for

Answer 1

Use $:

Pattern p = Pattern.compile("s$");

Answer 2

take a look for following example:

String ss = "Developers".replaceAll(".$", " ");

Answer 3

You need to match "s", but only if it is the last character in a word. This is achieved with the boundary assertion $:

input.replaceAll("s$", " ");

If you enhance the regular expression, you can replace multiple suffixes with one call to replaceAll:

input.replaceAll("(ed|s)$", " ");

Answer 4

    public static void main(String[] args) 
{
    String message = "hi this message is a test message";
    message = message.replaceAll("message$", "email");
    System.out.println(message);
}
