Question

Okay so, I have to use an interface in a code I’m making involving currency and there are some methods I’ve created with parameters. Question: Does it matter if I create the my interface class with different parameter names than the classes that are implementing it?

For example:

//One of my methods which calculates a US paper currency (created in my interface class)
BigDecimal getUSD(int onepaper, int fiftypaper, int twentypaper,  int tenpaper, int fivepaper, int onepaperval);

//One of my classes which contains the getUSD method in it.
public void getUSD(int dollars, int quarters, 
        int dimes, int nickels, int pennies)
{
    payment = dollars + quarters * QUARTER_VALUE + dimes * DIME_VALUE
            + nickels * NICKEL_VALUE + pennies * PENNY_VALUE;
}

Will this create an issue when java runs? (Note this is my first time using interfaces)

Answer 1

It does not matter what you name your variables as long as they are in the same order and of the same type as the interface.
