Regular Expression "Z" Metacharacter in Java

The subexpression/metacharacter “\Z” matches the end of the entire string except allowable final line terminator.

Example 1

import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class RegexExample {
   public static void main( String args[] ) {
      String regex = "Tutorialspoint\z";
      String input = "Hi how are you welcome to Tutorialspoint";
      Pattern p = Pattern.compile(regex);
      Matcher m = p.matcher(input);
      int count = 0;
      while(m.find()) {
         count++;
      }
      System.out.println("Number of matches: "+count);
   }
}

Output

Number of matches: 1

Example 2

The following Java program verifies whether the given input text ends with a digit.

import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class Data {
   public static void main( String args[] ) {
      String regex = "[0-9]\z";
      String input = "Hi how are you \n this is sample text \n this is third line 554";
      Pattern p = Pattern.compile(regex);
      Matcher m = p.matcher(input);
      if(m.find()) {
         System.out.println("Given input ends with a digit");
      } else {
         System.out.println("Given input doesn’t end with a digit");
      }
   }
}

Output

Given input ends with a digit
