Method Overload -

I created three method overloads.

1.) 68 inches to cm
2.) 5 foot 8 inches to cm
3.) 5.667 foot to cm

import java.text.DecimalFormat;

public class ConverttoCM {
    public static void main(String[] args) {
        System.out.println("68 inches equals " + convertToCentimeters(68) + " cm");

        // 5 foot 8 inches =- 68 inches
        System.out.println("5 foot and 8 inches equals " + convertToCentimeters(5, 8) + " cm");

        // 5.667 feet = 58 inches
        DecimalFormat f = new DecimalFormat("##.00");
        System.out.println("5.67 foot equals " + f.format(convertToCentimeters(5.6667)) + " cm");
    }

    public static double convertToCentimeters(int inches) {
        return (inches * 2.54);
    }

    public static double convertToCentimeters(double feet) {
        return (feet * 12 * 2.54 * 100) / 100;
    }

    public static double convertToCentimeters(int feet, int inches) {
        return ((feet * 12 + inches) * 2.54);
    }
}

This code does area of both circle and rectangle. It looks for negative units.

1.) single variable is for a circle

2.) two variables are for a rectangle or square

public class Area {
    public static void main(String[] args) {
        area(5.0 );
        area(-1 );
        area(1 );
        area( 4,5);
        area(-4, 5);
        area(4, -5);
    }

    private static void area(double a) {
        if (a < 0) {
            System.out.println(a + " is not a value");
        }
        else {
            System.out.printf("Circle with a unit of " + a + " has an area of ");
            printOut(a * a * Math.PI);

        }
    }

    private static void area(double a, double b) {
        if ( (a < 0) || (b < 0) ) {
            System.out.println( a + " or " + b +" is negative");
        }
        else {
            System.out.printf("A rectangle with a unit of " + a + " and " + b +" has an area of ");
            printOut(a * b);

        }
    }

    private static void printOut (double result) {
            System.out.println(result + " units");
        }

    }
