METHODS - Introduction to Java Programming: Comprehensive Version - page 236

Write a test program that invokes these methods to display the following tables:

Celsius Fahrenheit | Fahrenheit Celsius

40.0 104.0 | 120.0 48.89

39.0 102.2 | 110.0 43.33

...
32.0 89.6 | 40.0 4.44

31.0 87.8 | 30.0 -1.11

( Conversions between feet and meters ) Write a class that contains the following
two methods:

/** Convert from feet to meters */
public static double footToMeter( double foot)

/** Convert from meters to feet */
public static double meterToFoot( double meter)

The formula for the conversion is:

meter = 0.305 * foot
foot = 3.279 * meter

Write a test program that invokes these methods to display the following tables:

Feet Meters | Meters Feet

1.0 0.305 | 20.0 65.574

2.0 0.610 | 25.0 81.967

...
9.0

2.745 | 60.0 196.721

10.0 3.050 | 65.0 213.115

( Use the isPrime Method ) Listing 6.7, PrimeNumberMethod.java, provides the
isPrime(int number) method for testing whether a number is prime. Use this
method to find the number of prime numbers less than 10000 .

6.11

( Financial application: compute commissions ) Write a method that computes the
commission, using the scheme in Programming Exercise 5.39. The header of the
method is as follows:

public static double computeCommission( double salesAmount)

Write a test program that displays the following table:

Sales Amount Commission

10000 900.0

15000 1500.0

...
95000 11100.0

100000 11700.0
