Question

Write an application that accepts up to 20 Strings. Divide them into two lists—one for short Strings that are five characters or fewer, and the other for long Strings. After data entry is complete, prompt the user to enter which type of String to display, and then output the correct list. If there are no Strings in a requested list, then output an appropriate message. Save the file as DivideStrings.java.

Again, don’t forget to create the application/project DivideStringsTest.java Class that has the main method and an object to use the DivideStrings class.

Explanation / Answer

DivideStrings.java

package org.students;

import java.util.ArrayList;
import java.util.Scanner;

public class DivideStrings {

   public static void main(String[] args) {
       ArrayList<String> al = new ArrayList();
       ArrayList<String> al1 = new ArrayList();
       Scanner sc = new Scanner(System.in);
       for (int i = 0; i < 20; i++) {
           System.out.print("Enter a String " + (i + 1) + " :");
           String str = sc.nextLine();
           if (str.length() <= 5) {
               al.add(str);
           } else {
               al1.add(str);
           }

       }
       System.out.println("The Short Strings You Entered Are ::");
       for (String s : al) {
           if (s.isEmpty()) {
               System.out.println(":: YOU DIDNT ENTERED ANY SHORT STRINGS ::");
           } else {

               System.out.println(s);
           }
       }
       System.out.println(" ");
       System.out.println("The Long Strings You Entered Are ::");
       for (String s : al1) {
           if (s.isEmpty()) {
               System.out.println(":: YOU DIDNT ENTERED ANY LONG STRINGS ::");

           } else {

               System.out.println(s);
           }
       }
   }

}
