public class JavaSpliteString {
 public static void main(String[] args) {
 String original;
 Scanner scanner = new Scanner(System.in);
 System.out.println("Enter a string:");
 original = scanner.nextLine();
 
 //split String to array splited with whitespace regex
 String[] splittedStringArray = original.split("\\s+");
 System.out.println("length = " + splittedStringArray.length);
 
 for(String s : splittedStringArray){
 System.out.println(s);
 }
 
 //Join the String array to a String using StringBuilder
 StringBuilder stringBuilder = new StringBuilder();
 for(String s : splittedStringArray){
 stringBuilder.append(s);
 }
 System.out.println(stringBuilder);
 }
