How to add coins from different currencies

We are teaching a class where we need to teach about currency. We would like our students to add and demonstrate using different currencies across the world.

(e.g. Country=US, How much does 3 nickels + 2 pennies + 3 dimes)
(e.g. Country=UK, ...)
(e.g. Country=JAPAN, ...)
(e.g. Country=CHINA, ....)
(e.g. Country=AUSTRALIA, ...)

Is there any sample code, which demonstrates conversion of coins in different currencies?

Note: If it also contains the conversion between smaller units (e.g. b/w nickels, pennies, dimes, dollar) it would be useful.

Java enumerations are a nice tool. You can create one for each currency:

public enum US
{
  PENNY(1),
  NICKLE(5),
  DIME(5),
  QUARTER(1);

  int value;
  US(int i)
  {
    value = i;
  }

  public int getValue()
  {
    return value;
  }
}

This code shows how to use it:

public class Driver
{
  public static void main(String[] args)
  {
    System.out.println("Total value is " + (US.NICKLE.getValue() * 3 + US.QUARTER.getValue() * 2 + US.PENNY.getValue() * 4));
  }
}
