Question

Exercise 1): take the program “InteractiveCounting” (attached). Your task is to change the implementation of both the “ReadInput” and the “Count” classes. Currently these classes extends Thread. You should now use the Runnable interface to implement the thread. The output of the program should not change.

I have also attached the class ThreadType2 to give you a working example on how to implement a thread using the Runnable interfacethe program is here

package threadExamples;
import java.util.Scanner;

public class InteractiveCounting {

        static InteractiveCounting ic;
        static InteractiveCounting.ReadInput ri;
        static InteractiveCounting.Count c;

        public static void main( String args[] ){

                ic = new InteractiveCounting();

                c = ic.new Count();
                c.start();

                ri = ic.new ReadInput();
                ri.start();

        }

        class ReadInput extends Thread{

                Scanner scanner = new Scanner(System.in);
                int numberGap;

                void read(){
                        while(true){
                                System.out.print( "\nThis is thread:" + getName());
                                System.out.print( " => Enter number: \n" );
                                InteractiveCounting.c.numberGap = scanner.nextInt();
                        }
                }

                public void run(){
                        read();
                }

        }

        class Count extends Thread{

                int total = 0;
                int numberGap = 1;

                void count(){
                        while(true){
                                total = total + numberGap;
                                System.out.println();
                                System.out.print( "This is thread:" + getName() );
                                System.out.println( " => " + total );
                                try {
                                        Thread.sleep( 3000 );
                                } catch (InterruptedException e) {
                                        // TODO Auto-generated catch block
                                        e.printStackTrace();
                                }
                        }
                }

                public void run(){
                        count();
                }
        }

}

threadtype2 program

package threadExamples;

public class ThreadType2 implements Runnable {

    public void run() {
        System.out.println("Hello from a thread implemented through the Runnable interface!");
    }

    public static void main(String args[]) {
        (new Thread(new ThreadType2())).start();
    }

}
