how to generate 10 random card Images in applet graphics
Please help me How can I generate random cards, cards is have type Image img;
So I want to draw random 10 random cards from 104, I have tied but not solving, please help me.......

Re: how to generate 10 random card Images in applet graphics
Just put your images in an array, then generate 10 random numbers and use them as indexes. Or put all your cards in a List, shuffle the list, and take the first 10 elements.
Re: how to generate 10 random card Images in applet graphics
I have tried to put all the images in an array but not getting out put, please give me the solution where and how array will be used for draw random images....

Can you show your problem with using an array?
Re: how to generate 10 random card Images in applet graphics
I have declared array list of card as static ArrayList<Image> card;
and draw g.drawImage( card.remove(ran.nextInt(card.size())), c.x,c.y, this );
but not generate random images
I have also tried with bufferimage also for creation a variable and store all the cards images and then generate random images but not solving,
Please you help me and give solution step by step that I will do,.

Post the code that you tried to use and post the error messages.
Quote:
card.remove(ran.nextInt(card.size()))
Break this compound statement into single statements and print out the results of each.

And Also Error at the following line

This line generate error, please tell me where I am wrong.

Can you explain why the selected images did not work?

As I have recommended twice before:

card.remove(ran.nextInt(card.size()))

System.out.println( card.remove(ran.nextInt(card.size())));

Re: how to generate 10 random card Images in applet graphics
No.
Break this compound statement into single statements and print out the results of each.
There are three sub parts to that statement, print each one separately.

System.out.println( card.remove(ran.nextInt(card.size())));

This is the part I was talking about: card.remove(ran.nextInt(card.size())));
Break it up and print The results of these methods:
size()

On line 168, Make sure n is a positive number.
Re: how to generate 10 random card Images in applet graphics
If you really want any help with this problem, you MUST post a small, simple program that compiles, executes and shows the problem.
Posting 2 lines of code and a hundred lines of error message text is a big waste of time.
Re: how to generate 10 random card Images in applet graphics
Ok, now this line generate n must be positive error.
g.drawImage( card.remove(ran.nextInt(card.size())), x1[j],y1[j], this );
so where I am wrong.......
