overriding methods

[stunaep via Digitalmars-d-learn]

I get a deprecation warning with @Override, but I was unable to 
find the proper way to do it.
Am I meant to add override before the method like this?
>override public void startThread(Thread t, int pri) {
>    ...
>}
Am I meant to wrap the entire method in override { } like this?
> override {
>    public void startThread(Thread t, int pri) {
>        ...
>    }
> }

Both of them compile, so I'm wondering which to use. Is override 
{} supposed to be for adding multiple methods inside to avoid 
writing override before each method, or is putting override in 
front of the method without brackets just wrong?
