Question

Hello,

so I need someone to look over this code and see if im on the right path. I feel like im

missing something.

Here is the assignment:

Create a class called Slogans. This class will extend the Thread class. This thread will read from a file several quotes that are on each line. It will pick a quote randomly and display it to the console. It will change quotes every 7 seconds. This will be updated in the final project to display in a GUI.

Here are the quotes I need to display:

May the force be with you

Don't cross the streams

Live long and prosper

I'll be back

Strength and honor

Yo, Adrian

Autobots, transform and roll out

Hulk Smash!

With great power comes great responsibility

There is only one thing we say to death: not today

Here is the code:

I started off with this:

public class Main implements Runnable {

String msg;

Main(String s)

{

msg=s;

}

public static void main(String[] args) {

Thread t1 = new Thread(new Main("m"));

Thread t2 = new Thread(new Main("n"));

t1.start();

t2.start();

}

public void main(String[] args){

}

I'm sorry the language is for Java.

Hello,

Please remember to upvote the answer if it helps you. Below is the code .only thing you need to change is provide the location to your text file.

=============================================================================================

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Random;
import java.util.Scanner;

class Slogans extends Thread {
   final long timeInterval = 7000;

   @Override
   public void run() {
       //This is the simple implementation to run the thread for every 7 sec
       while (true) {
           String s = null;
           try {
               //Provide your text file location here.
               s = choose(new File("C:\\Working\\sts-bundle\\workspace\\springMVC4\\Chegg\\File.txt"));
               System.out.println(s);
               Thread.sleep(timeInterval);
           } catch (FileNotFoundException e) {
               e.printStackTrace();
           } catch (InterruptedException e) {
               e.printStackTrace();
           }
       }

   }

   public String choose(File f) throws FileNotFoundException {
       String result = null;
       //To pick any random lines from file
       Random rand = new Random();
       int n = 0;
       //Scanner is reading the file line by line. This type of pattern is called
       //RESERVIOUR_SAMPLING.
       for (Scanner sc = new Scanner(f); sc.hasNext();) {
           ++n;
           String line = sc.nextLine();
           if (rand.nextInt(n) == 0)
               result = line;
       }
       return result;
   }

}
=================================================================================

public class Main {
   public static void main(String[] args) {
       Slogans thread=new Slogans();
       thread.start();
   }
}
