How to call a method after a delay in Android

I want to be able to call the following method after a specified delay.
In objective c there was something like:

[self performSelector:@selector(DoSomething) withObject:nil afterDelay:5];

Is there an equivalent of this method in android with java?
For example I need to be able to call a method after 5 seconds.

public void DoSomething()
{
     //do something here
}
