I am studying garbage collection in Java. It says "the method getRuntime returns a Singleton. we can invoke gc() on this." What is meant by Singleton? What does it mean when we say the current runtime can be obtained from the getRuntime method?
Mansukhdeep, that's a good question to answer by using Google. Lots of people here know the answer, but you should consider a number of different ways to state it, which you will obtain if you use something like Google. Also, by using Google for a well-defined question that has a straightforward answer, you will find lots of useful Web sites that can help you when you have other questions about Java.

What's "it"? The getRuntime method returns a Runtime object associated with the current application.
