Method Detail

main

public static void main(java.lang.String[] args)

simlights

public double simlights(int offset,
                        int span,
                        double arrivalProb,
                        int travelTime,
                        int totalTime)

printNumber

public static void printNumber(double d,
                               int minimumWidth,
                               int fractionDigits)

Print a number to System.out, using a specified format.

Parameters:

d - the number to be printed

minimumWidth - the minimum number of characters in the entire output

fractionDigits - the number of digits to print on the right side of the decimal point

Precondition:

fractionDigits is not negative.

Postcondition:

The number d has been printed to System.out. This printed number is rounded to the specified number of digits on the right of the decimal. If fractionDigits is 0, then only the integer part of d is printed. If necessary, spaces appear at the front of the number to raise the total number of printed characters to the minimum. Additional formatting details are obtained from the current locale. For example, in the United States, a period is used for the decimal and commas are used to separate groups of integer digits.

Throws:

IllegalArgumentException - Indicates that fractionDigits is negative.

Example:

printNumber(12345.27, 8, 1);
Prints 12,345.3 in the U.S.
