Hello.

I am currently attempting to create a program that uses the method 'waitNSeconds' to wait a different number of seconds before displaying the number of each different bank note, displayed at the bottom of the program, but when trying to compile the program I keep getting the error 'cannot find symbol' on the line 'wait1second' in my for loop.

Here's what I have so far:

public class BankTeller1
{

public static void waitNSeconds(int number)
{
int i;
for (i = 0; i < number; i++)
{
wait1second();
}
}

public static void main (String args[])
{
// declare and initialise variables
int Sterling = 77;
String indent = " ";
int Hundreds, Fifties, Twenties, Tens, Fives,Ones;

// Convert sterling amount into a working number of pounds
Ones = Sterling;

// perform calculations

// How many hundreds?
Hundreds = Ones / 100;

// Carry forward whatever is left
Ones = Ones % 100;

// How many fifties?
Fifties = Ones / 50;

// Carry forward whatever is left
Ones = Ones % 50;

// How many twenties?
Twenties = Ones / 20;

// Carry forward, and so on
Ones = Ones % 20;

Tens = Ones / 10;
Ones = Ones % 10;

// How many fives?
Fives = Ones / 5;

// Carry forward, and so on
Ones = Ones % 5;

// output results
System.out.println("The notes are :");
System.out.println();
System.out.println(indent + "Fifties : " + Fifties);
System.out.println(indent + "Twenties : " + Twenties );
System.out.println(indent + "Tens : " + Tens );
System.out.println(indent + "One pound coins :" + Ones);
System.out.println();
System.out.println("Total: " + Sterling + " pounds");

}
}


Any help/advice would be greatly appreciated.

do you have a method defined somewhere named "wait1second()"? There certainly isn't one here in the code you posted.

Not at the moment, no. ^^;;

I wasn't entirely certain on how to define one.

Okay, I've managed to include a 'wait1second' method which seems to have helped with the "error: cannot find symbol" problem.

I just can't seem to work out how to call the 'waitNSeconds' method, so that it waits a specific length of time before displaying each piece of information.

Welcome to the Ranch
I can give you a hint:There are methods which suspend execution, eg Thread#sleep, but that take milliseconds as its parameter. The best way to turn seconds to milliseconds is probably via the TimeUnit enumeration.
Don’t write wait1Second(), wait2Seconds(), wait3Seconds() etc.

It's okay, I've got it working now.

But thanks for the tips anyway, guys.
