The document describes a class with two methods to convert between feet and meters. The footToMeter method converts from feet to meters using the formula meters = 0.305 * feet. The meterToFoot method converts from meters to feet using the formula feet = 3.279 * meters. A test program is provided that uses these methods to output conversion tables from 1 to 10 feet and from 20 to 65 meters.

1. (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 | 1.0 0.305 | 2.0 0.610 | ... 9.0 2.745 | 10.0 3.050 | Meters Feet 20.0 65.574 25.0
81.967 60.0 196.721 65.0 213.115

class Programming {
public static void main(String[] args) {
System.out.printf("%-15s%-15s| %-15s%-15s ","Feet","Meters","Meters","Feet");
System.out.println( String.format("%62s"," ").replace(' ', '-') );
for (int m = 20, f = 1 ; f <=10; f++, m+=5) {
System.out.printf("%-15.1f%-15.3f| %-15.1f%-15.3f ",(float)f,
footToMeter(f),(float)m,meterToFoot(m));
}
}

2. /** Convert from meter to foot */
public static double meterToFoot(double meter) {
return 3.279 * meter;
}
/** Convert from foot to meter */
public static double footToMeter(double foot) {
return 0.305 * foot;
}
}
Output:
Feet Meters | Meters Feet
