Thread: Checking memory allocation

I need to check that memory was successfully allocated in the following (very, very basic) code. How do I check it? Apparently one option is to use a try....catch block. But what exactly would I be catching?

And why do I even need to check this?

public class Square
{
        // Data members
        final int r = 10;
        final int c = 10;
 
        Cell[][] square;
 
        public Square()
        {
                square = new Cell[r][c];
         }
}

Haha, I take it you are a C/C++ coder ? Anyways, don't worry about it, Java takes care of allocation and garbage collection for you. All you need to do is instantiate the object:

Square mySquare = new Square();

This object, 'mySquare' has a place in memory and will get cleaned up when it falls out of scope or when the program ends.

Oh, and try / catch blocks are for exception handling. When something goes wrong at run-time Java throws a stack of exceptions. 'try' attempts to run some code and 'catch' does something when it f's up.

Yeah, I am from C++ lol.

Thanks for the help guys!
