Metric Makes the World Go Round

| Posted in , , | Posted on 5:56 PM

I'm always a fan of European things. Most often this means cars & food. The metric system though... is something I could take or leave. Like most Americans I don't have a natural sense of how far a kilometer is or how heavy a kilogram weighs. Either of these has to be converted into something in the Standard measurement before anything meaningful can be understood. Thank god for Java.

This is a program which will convert a length in feet into a length in meters.


/*
 * This is a simple program to convert feet into meters. Feet are entered
 * as a double value, converted into meters as a double value, and then output.
 * In/out dialogs are generated using the swing JOptionPane class.
 */

package feet2meters;

import javax.swing.JOptionPane;

/**

public class Main {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {

        //prompt the user to enter the number of feet to be converted
        //and store as a string value
        String stringFeet = JOptionPane.showInputDialog (null,
                "Enter the number of feet to be converted to meters",
                "Feet2Meters!", JOptionPane.QUESTION_MESSAGE);

        //convert feet string value into a double variable
        double feet = Double.parseDouble(stringFeet);

        //initialize meters as double variable and calculate value
        double meters = feet * 0.305;

        //display number of meters calculated from feet given
        JOptionPane.showMessageDialog(null, feet + " feet is equal to " +
                meters + " meters.", "Feet2Meters!",
                JOptionPane.QUESTION_MESSAGE);

    }

}
