Write a Java application that displays two dialog boxes in sequence. The first asks
you to think of a number between 1 and 10. The second displays a randomly
generated number; the user can see whether his or her guess was accurate.
public class randomnumber {
public static void main(String[] args) {
JOptionPane.showMessageDialog(null,"Just Think any NUmber between 1 to 10");
JOptionPane.showMessageDialog(null,"The number is " +
(1 + (int)(Math.random() * 10)));
}
}
Explanation
In order to write a Java application that displays two dialog boxes in sequence, we need to first understand the basics of Java GUI programming. The Java programming language provides a built-in package called “javax.swing” that contains all the necessary classes and methods for creating graphical user interfaces.
The first step in creating this application is to create a Java class that extends the JFrame class. This class will serve as the main window for our application and will contain the dialog boxes.
Next, we need to create two instances of the JOptionPane class. The first JOptionPane instance will be used to prompt the user to think of a number between 1 and 10. The second JOptionPane instance will be used to display a randomly generated number.
To display the first dialog box, we will use the showInputDialog method of the JOptionPane class. This method takes a string argument that is the prompt that will be displayed to the user. In this case, the prompt will ask the user to think of a number between 1 and 10.
The second dialog box will be displayed using the showMessageDialog method of the JOptionPane class. This method takes two arguments: a JFrame instance that serves as the parent component of the dialog box, and a string argument that is the message that will be displayed to the user. In this case, the message will be the randomly generated number.
To generate a random number, we can use the Math.random method. This method returns a random decimal number between 0 and 1. We can then multiply this number by 10 and use the Math.floor method to round it down to the nearest integer. This integer will be our randomly generated number.
Finally, we can compare the user’s guess with the randomly generated number and display a message indicating whether the guess was accurate or not.
In summary, this Java application will display two dialog boxes in sequence. The first will ask the user to think of a number between 1 and 10. The second will display a randomly generated number, and the user can see whether their guess was accurate.
