Split string after each character using regular expression

     

This Example describes the way to split the String after each character using expression. For this we are going to make program named SplittingFind. java. The steps involved in program SplittingFind.java are described below:

String regex = ("\\w.+"):- Creating expression for text. Here "\\w" means to match any alphanumeric character.

Pattern p = Pattern.compile(regex):- Creating a pattern object and compiles the given regular expression into a pattern.

Matcher m = p.matcher(text):- Creates a matcher for matching the given input against pattern p.

m.find():- This is the method of matcher class which is used for finding the next subsequence of the input sequence and it usually returns a boolean value.

m.group():- It returns the input sequence match with the first match.

SplittingFind.java

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class SplittingFind {

  public static void main(String[] args) {
  String regex = ("\\w.+");
  Pattern p = Pattern.compile(regex);
  String text = "Roseindia.net Rohini";
  Matcher m = p.matcher(text);
  System.out.print("Text is:");
  while (m.find()) {
  System.out.print(m.group());
  }
  System.out.println();
  int i = 0;
  while (m.find(i)) {
  System.out.print(m.group() + "\n");
  i++;
  }
  }
}

Output of the program:-

Text is:Roseindia.net Rohini
======================
Roseindia.net Rohini
oseindia.net Rohini
seindia.net Rohini
eindia.net Rohini
india.net Rohini
ndia.net Rohini
