Hey all, just a quick question. Are lambda expressions just a replacement for anonymous classes or are they for something more?

I really don't mind doing, for example:

SwingUtilities.invokeLater(new Runnable(){
    public void run(){
        new ClassName();
   }
});

Although It does look a little nicer with the lambdas

SwingUtilities.invokeLater(() ->{
    new ClassName();
});

Is it all about saving a line or two? Is this something I should just start doing instead of anonymous classes or does it even matter?
