What is Singleton

[Mansukhdeep Thind]

Hi

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?

What is meant by Singleton?

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 does it mean when we say the current runtime can be obtained from the getRuntime method?

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