Java syntax confusion in OnClickListener

I am a newbie in Android Development, how can I understand this snippets?

private OnClickListener listener = new OnClickListener() 
{   
    @Override
    public void onClick(View v)
    {
        // TODO Auto-generated method stub
        System.exit(0);
        finish();
    }
};

OnClickListener is a static interface, we can't use "new" to initialize an object. Who can help me, thank you in advance.

In Java, you can create an Anonymous Class if you implement all necessary requirements of the interface being presented. This is acting as a new class definition implementing OnClickListener, and overriding its one necessary method, onClick(View).
