java : anonymous class

In java this is valid

new Thread(new Runnable()
    {   
        public void run()
        {
            for(int i=0;i<5;i++)
                System.out.println("From anonymous:"+i);
        }
    }   
).start();

But this is not :

Thread t=new Thread(new Runnable()
    {   
        public void run()
        {
            for(int i=0;i<5;i++)
                System.out.println("From anonymous:"+i);
        }
    }   
).start();

can I achieve it with anonymous class? If yes then How

One thing to note here is that the start method of Thread returns void. This is why you cannot assign it to a variable.

Also, in this case you don't need to use Runnable interface because is implemented by the Thread class.

    new Thread() {
        @Override
        public void run() {
            for(int i=0;i<5;i++)
               System.out.println("From anonymous:"+i);
        }
    }.start();

Your code does not work, because it wants to assign the result of the start() method to the variable t. You can do it like so:

Thread t=new Thread(new Runnable()
    {   
        public void run()
        {
            for(int i=0;i<5;i++)
                System.out.println("From anonymous:"+i);
        }
    }   
);
t.start();
