How to set Main to access methods

Posted: Feb 14, 2003 9:13 PM

I am starting to learn java programming. I would like to know how to setup the main to access the methods. Enclosed is an example of code, would like to know how to design the main to access the method class.

public class Dollars
{
/***************************************************************
*Outputs amount in dollars and cents notation. Rounds after two
*decimal points. Does not advance to the next line after output.
***************************************************************/
public static void write(double amount)
{
if (amount >= 0)
{
System.out.print('$');
writePositive(amount);
}
else
{
double positiveAmount = -amount;
System.out.print('$');
System.out.print('-');
writePositive(positiveAmount);
}
}

//Precondition: amount >= 0;
//Outputs amount in dollars and cents notation. Rounds
//after two decimal points. Omits the dollar sign.
private static void writePositive(double amount)
{
int allCents = (int)(Math.round(amount*100));
int dollars = allCents/100;
int cents = allCents%100;

System.out.print(dollars);
System.out.print('.');
if (cents < 10)
{
System.out.print('0');
System.out.print(cents);
}
else
System.out.print(cents);
}

/***********************************************************
*Outputs amount in dollars and cents notation. Rounds after
*two decimal points. Advances to the next line after output.
***********************************************************/
public static void writeln(double amount)
{
write(amount);
System.out.println();
}

}
