Why not? Look at the top right of the page. Just under the words "The Big Moose Saloon" there is a whole list of links. The top left link is titled "Search". Click on that. It will take you to a page where you can fill in what to search for. Type in some words, for example "heap memory" and click the search button. Then look if it found something interesting. Ofcourse you could also search on Google, for example for "java heap stack".
The heap is the main area of memory where all objects are stored.
The
stack is a special memory area where local variables are allocated and where other information is stored that is necessary for nested method calls, such as where execution should go to when the method finishes.
