Thread start, run question

Question

public class Test {
     public Test(){
          boolean a=false;
          Thread t = new Thread() {
            public void run() {
                 //code a
    if(a){
         //comment 1: here I need to execute the code a and code b concurrently
         t.start();
    }else{
         //comment 2:here I don't want a concurrent process and code b starts only after completion of code a
         t.run();
     //code b     
     public static void main(String args[]){
          new Test();
      * I know that if the 'code a' is in a method() then its ok that we can call that
      * method instead of t.run(); . But this application already developed like this.
}My question is : Is the above implementation on right way to satify comment1 and comment2 ?

Answer 1

It works the same way that anonymous subclasses of Classes work. The only difference is that you need to implement every method of that interface (which is only one in the case of Runnable).
So if
Thread t = new Thread() {
  //some methods
};is a shortcut for
//outside your method, but inside your (outer) class:
class MyAnonymousThread extends Thread{
  //some methods
//inside your method:
Thread t = new MyAnonymousThread();then
Runnable r = new Runnable() {
  //some methods
};is a shortcut for
//outside your method, but inside your (outer) class:
class MyAnonymousRunnable implements Runnable {
  //some methods
//inside your method:
Runnable r = new MyAnonymousRunnable();(note that those are not completely the same, since you can access final local variables of your method inside a anyonymous inner class among )
