What have you tried so far? According to what you posted, no effort has been put into the work. This is not a place to get others to do your homework or spoon-feed. Check out the tutorials on conditional statement and then try again. If you get an error, post here and we might help you.

here is what i did :
public static void main(String[] args) {
int balance= 0;
int deposit = 0;

String a =(JOptionPane.showInputDialog(null, "Automatic Teller Machine\n [B] Balance Inquiry\n [D]Deposit\n [W] Withdrawal\n [Q] Quit\n Select you Options: ","Automatic Teller Machine",JOptionPane.PLAIN_MESSAGE));

String B= "";
if (a == B)//checking for input 1
{
JOptionPane.showMessageDialog(null, "Your Balance is: ");




}










}

}


(im sorry if u think that this contains othing, ive been erasing then typing again im really sorry im a beginner)

if (a == B)

One problem you might have is using == for comparing the contents of two Strings.
You should use the equals() method for that.

To make it easier for potential helpers, enclose your code with [highlight = java] Your Code Here [/java]. Doing so will highlight your code and make it easier to read.

According to my information you should try to make use of switch block for this program. and that will be better to make these conditional based prog..
