how to remove ing from the end of word using regex in java

Question

I want to remove "ing" from word, example i want "watching" become "watch" by removing "ing" from the end of the word. Using regex in java.

i use this pattern:

String pattern = "$ing";

and use it to remove:

String word = "watching";
word = word.replaceAll(pattern,"");

but the result is still "watching" not "watch"

Answer 1

Put the dollar sign at the last, so that it matches the last ing. $ is an anchor which represents End of the line.

Example:

System.out.println("watching".replaceAll("ing$", ""));
