Hi,
Why don't you start your demo like this?
import java.io.IOException;
public class Demo {
     public Demo() {
     public void startDemo() throws IOException {
          do {
               System.out.println("String Console Demo ");
               System.out.println("\t" + "1. Queue Demo");
               System.out.println("\t" + "2. PriorityQueue Demo");
               System.out.println("\t" + "3. LinkedList Demo");
               System.out.println("\t" + "4. PrintJob Demo");
               System.out.println("Please choose one option");
               choice = (char) System.in.read();
               showDemo(choice);
          } while (choice < '1' || choice > '4');
     public void showDemo(char ch) {
          switch (ch) {
          case '1':
               System.out.println("You have chosen Queue Demo ");
               showOperations();
               break;
          case '2':
               System.out.println("You have chosen Priority Queue Demo ");
               showOperations();
               break;
          case '3':
               System.out.println("You have chosen LinkedList Demo ");
               showOperations();
               break;
          case '4':
               System.out.println("You have chosen Print Job Demo ");
               showOperations();
               break;
     private void showOperations() {
          System.out.println("Please choose any operations ");
          System.out.println("\t" + "1. Insert ");
          System.out.println("\t" + "2. Remove ");
          System.out.println("\t" + "3. Reset ");
          System.out.println("\t" + "4. search ");
     public static void main(String[] args) throws IOException {
          Demo demo = new Demo();
          demo.startDemo();
     private char choice;
Write a separate classes for the data structures show the initial elements and call the methods based on the operations then show the result.
Thanks
