Running two functions with threading

I have a class with name Socket that have tow function for example func1 and func2 

fucn1() {
    while(true) {
        ...
    }
}

fucn2() {
    while(true) {
        ...
    }
}

I want two of them run with thread in a time and concurrently. how can i do that?? 

class socket implement Runnable {
    public void run() {
        func1();
        func2();
    }
}

In this code only first function is executed not second. How can i do for concurrently run both of them?

My Suggestion is :

Instead of making socket Class Runnable, Create two Runnable threads as in my example below and call your functions from there. And start these two threads from your Socket class.

class Socket{
    private void startThreads() {
          new Thread(new Th1()).start();
          new Thread(new Th2()).start();

    }
}
class Th1 implements Runnable {
    @Override
    public void run() {
        fucn1();
    }
}
class Th2 implements Runnable {
    @Override
    public void run() {
        fucn2();
    }
}

You can run them concurrently like this:

// start a thread for func1
Thread t1 = new Thread(new Runnable() {
       public void run() { 
           func1();
       }
    });
 t1.start();

 // func2 will run in parallel on the main thread
 func2();

 t1.join(); // if you want to wait for func1 to finish.

You haven't given any details, so I'm assuming they have no side-effects.

You need to create two threads for this scenario. 

class socket implement runable
{
    boolean condition;

    public socket(boolean condition){
         this.condition = condition;
    }
    public void run()
   {
      if(condition == true){
            func1();
      }else{
           func2();        
      }
   }
}

Thread t1 = new Thread(new Socket(true));
Thread t1 = new Thread(new Socket(false));


  t1.start();
    t2.start();

In addition to this you need to yield control in each method just to make sure that every thread will get fair chance to run.

If you want to run the two functions concurrently, spawn two threads and run each function in its own thread.

That's precisely what threads are for.
