splitAsStream() method in Java's pattern and its example

The Pattern class in the java.util.regex package is the compiled representation of regular expressions.

This class's splitAsStream() method accepts a CharSequence object, which represents the input string as a parameter, and in each match, it splits the given string into a new substring, and returns the result as a stream containing all substrings.

Example

import java.util.regex.Pattern;
import java.util.stream.Stream;
public class SplitAsStreamMethodExample {
　　　public static void main( String args[] ) {
　　　　　　//Regular expression to find numbers
　　　　　　String regex = "(\\s)(\\d)(\\s)";
　　　　　　String input = "　1　Name: Radha, age:25　2　Name: Ramu, age:32"　+　"　3　Name: Rajeev, age:45　4　Name: Raghu, age:35"　+　"　5　Name: Rahman, age:30";
　　　　　　//Compile regular expression
　　　　　　Pattern pattern = Pattern.compile(regex);
　　　　　　//Verify if a match occurs
　　　　　　if(pattern.matcher(input).find())
　　　　　　　　　System.out.println("Given String contains digits");
　　　　　　else
　　　　　　　　　System.out.println("Given String does not contain digits");
　　　　　　//Split String
　　　　　　Stream<String> stream = pattern.splitAsStream(input);
　　　　　　Object obj[] = stream.toArray();
　　　　　　for(int i = 0; i < obj.length; i++) {
　　　　　　　　　System.out.println(obj[i]);
　　　　　　}
　　　}
}

Output Result

Given String contains digits
Name: Radha, age:25
Name: Ramu, age:32
Name: Rajeev, age:45
Name: Raghu, age:35
Name: Rahman, age:30
