Drivers often want to know the miles per gallon their cars get so they can estimate gasoline costs. Develop an app that allows the user to input the number of miles driven and the number of gallons used and calculates and displays the corresponding miles per gallon.

Answer 1

Java Code:

import java.applet.*;

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

public class GuiGasMilage extends Applet implements ActionListener {

      TextField miles, gallons, milageCalculated;

      JButton calculate;

      JPanel buttonPanel;

      //You can change the class name with your name here

      public GuiGasMilage() {

            setLayout(new GridLayout(6,3));

            //You can change the color here

            setBackground(Color.blue);

            //Creating the text fields

            miles = new TextField(15);

            gallons = new TextField(15);

            milageCalculated= new TextField(15);

            calculate= new JButton();

            JButton calculate = new JButton("Calculate");

            calculate.addActionListener(this);

            //Press Enter when all the values are entered

            add(new Label("Enter Miles: "));

            add(miles);

            add(new Label("Enter Gallons: "));

            add(gallons);

            add(new Label("Milage miles/gallon:"));

            add(milageCalculated);

           

            add(calculate);

      }

      @Override

      public void actionPerformed(ActionEvent arg0) {

            // TODO Auto-generated method stub

            double mile = Double.parseDouble(miles.getText());

            double gallon = Double.parseDouble(gallons.getText());

            double milage = (mile)/(gallon);

            milageCalculated.setText("Milage: " + milage+" miles/gallon");

      }

}
