Code is running in multi-threading but it is neither pausing nor resuming..........

[pawan4angel]

I have created a JFrame here and you will also see JPanel and JLabel. I have also added two JButton "Pause" and "Resume" over there.

What I am trying to do is to pause and resume a child thread using JButtons, the program is running fine without any warning or errors, however, child thread is not pausing. The functions executes but it is not pausing the thread.

I have attached two text files. All the functions are executing in "Main.java" file and "child thread" code is written child_1.java.

Looking for quick help !!

Please post any code you are having problems with on the forum.

[pawan4angel]

I have already attached the files in 1st post, the name of the files are child_1.txt and Main.txt ........

Post the code in the thread, not as links.
Be sure to wrap the code in code tags.

Please edit your post and wrap your code with code tags:
[code=java]
<YOUR CODE HERE>
[/code]
to get highlighting and preserve formatting.

I have updated my post..........

[pawan4angel]

I have updated my post again, I dont know how to go further..............

[Norm]

Did you look at it to see that it was correctly formatted?
It should look like this

     public Scanner(Object o) {
        if (myScnr == null) {           //   Put responses here
           myScnr = new java.util.Scanner("1375 1.175 7 1 No\n");
        }
     }
     public Scanner(File f) throws FileNotFoundException {
       if(!f.exists())
          throw new FileNotFoundException(f.getName()); 
       //?????
       System.out.println(">>> No Scanner code for file: " + f);
     }
