ANSWERS TO PRACTICE PROBLEMS

// Problem 1.

import javax.swing.JOptionPane;
public class Main
{
    public static void main(String[] args)
    {
        String inputString;
        int celsius, fahrenheit;

        inputString = JOptionPane.showInputDialog(
            "Enter a temperature in Celsius.");
        celsius = Integer.parseInt(inputString);
        fahrenheit = 9 * celsius / 5 + 32;
        System.out.println("The temperature in Fahrenheit is " +
            fahrenheit + " degrees."); 
    }
}

// Problem 2.

import javax.swing.JOptionPane;
public class Main
{
    public static void main(String[] args)
    {
        String inputString;
        int number, output;

        inputString = JOptionPane.showInputDialog(
            "Enter an integer number.");
        number = Integer.parseInt(inputString);
        output = number % 2;
        System.out.println("The output is " + output + ".");
    }
}
