User Prompt Timer

[podonga poron]

The following code sets a timer task in console.

 
import java.util.Timer;
import java.util.TimerTask;
 
public class ToDo  {
  Timer timer;
 
  public ToDo ( int seconds )   {
    timer = new Timer (  ) ;
    timer.schedule ( new ToDoTask (  ) , seconds*1000 ) ;
  }
 
 
  class ToDoTask extends TimerTask  {
    public void run (  )   {
      System.out.println ( "Hello World" ) ;
      timer.cancel (  ) ; //Terminate the thread
    }
  }
 
 
  public static void main ( String args [  ]  )   {
    System.out.println ( "Schedule something to do in 5 seconds." ) ;
    new ToDo ( 5 ) ;
    System.out.println ( "Waiting." ) ;
     }
   }
}
 

But i want to implement a user prompt, to the code .. so the user can easily set the value of refreshing time ..

something like this ...

        System.out.println("Insert the refreshing time: ");
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        String time = br.readLine();

but the problem with this is i can't pass a String to the constructor ..

Is there a way to pass a int value, maybe with casting ? what is the correct way to do this ?

thanks a lot !

You can't do it with casting, because a String is simply not an int.

But you can parse a String as an int using the parseInt method of the Integer class...

int myInt = Integer.parseInt(myString);

WOW !! now it works ! THANKS !!

i leave the code maybe someone find it useful ..

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Timer;
import java.util.TimerTask;
 
public class ToDo{
  Timer timer;
 
  public ToDo (int myInt){
    timer = new Timer() ;
    timer.schedule (new ToDoTask() , myInt*1000) ;
  }
 
 
  class ToDoTask extends TimerTask{
      @Override
    public void run (){
      System.out.println ("Hello World !");
      timer.cancel() ; //Terminate the thread
    }
  }
 
 
  public static void main (String args[]) throws IOException{
    System.out.println("Insert the refreshing time: ");
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    String refreshingTime = br.readLine();
    int myInt = Integer.parseInt(refreshingTime);
    new ToDo (myInt) ;
    System.out.println ("Waiting ...") ;
     }
   }
