Trying to display a random card in a weird way with java

Right now I am trying to display a random card after defining a full deck. I was wondering if something along the lines of: 

g.drawImage( card (int) * (Math.random() * 52), 10, this);

will work. When I try to compile this, I get the following error:

 '.class' expected

 g.drawImage( card (int) * (Math.random() * 52), 10, this);

What I am trying to do here is since I have declared 52 cards named card0 - card51, I was trying to see if I could just write card then get a random number from 0 - 51 next to card.

I was wondering if this is a legitimate way of displaying a random card or, if I should go back to the drawing board.

I am a beginner in java and, do not understand many terms so please, try to keep your answers simple.

Thanks for all the help in advance.

No, that's not the way Java works. You can't use variable names determined at execution time.

Instead of having 52 separate variables, you should have an array or a collection:

private final Random random = new Random();
private final Card[] cards = new Card[52];
// Populate the array in the constructor, or wherever

...

// When you want to draw the card...
g.drawImage(cards[random.next(52)], 10, this);
