RegexReplace

Instructions

Create a file RegexReplace.java.

Write a function removeUnits that returns the string where the units cm and is removed if it followed directly a number and followed by a space.
Write a function removeFeminineAndPlural that returns the string where the mark of feminine and plural is removed from word :

  • if a word ends a mark of plural (with s or x), remove it.
  • if it ends with an e or if the e is followed by the mark of plural, remove the it
  • if it ends with le following el (or if le is followed by plural), remove it.

Expected Functions

public class RegexReplace {
    public static String removeUnits(String s) {
        // your code here
    }
    
    public static String removeFeminineAndPlural(String s) {
        // your code here
    }
}

Usage

Here is a possible ExerciseRunner.java to test your function
import java.io.IOException;

public class ExerciseRunner {
    public static void main(String[] args) throws IOException {
        System.out.println(RegexReplace.removeUnits("32cm et 50€"));
        System.out.println(RegexReplace.removeUnits("32 cm et 50 €"));
        System.out.println(RegexReplace.removeUnits("32cms et 50€!"));
        System.out.println(RegexReplace.removeFeminineAndPlural("le lapin joue à la belle balle avec des animaux rigolos pour gagner les billes bleues"));
    }
}

and its output :

$ javac *.java -d build
$ java -cp build ExerciseRunner 
32 et 50
32 cm et 5032cms et 50€!
l lapin jou à la bel ball avec d animau rigolo pour gagner l bill bleu
