The Pattern class of the java.util.regex package is a compiled representation of a regular expression.
The splitAsStream() method of this class accepts a CharSequence object, representing the input string as a parameter and, at each match, it splits the given string into a new substring and returns the result as a stream holding all the 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 digits 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"; //Compiling the regular expression Pattern pattern = Pattern.compile(regex); //verifying whether match occurred if(pattern.matcher(input).find()) System.out.println("Given String contains digits"); else System.out.println("Given String does not contain digits"); //Splitting the 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
Given String contains digits Name:Radha, age:25 Name:Ramu, age:32 Name:Rajeev, age:45 Name:Raghu, age:35 Name:Rahman, age:30
