Find Successively Repeated Character using Java

In this section, we are going to find the successively repeated character using Regular Expression. For this, we have specified a word 'programming' and with use of Pattern and Matcher class, we have found that 'm' is repeated successively.

Here is the code of Main_Class.java

import java.util.regex.*;

public class Main_Class{
public static void main(String[] args){
String st = "programming";
Pattern p = Pattern.compile("(\\w)\\1+");
Matcher m = p.matcher(st);
if (m.find()){
System.out.println("Repeated character is " + m.group(1));
}
}
}

Output:

Repeated Character is m
