Question

This statement tells the compiler where to find the JOptionPane class and makes it available to your program.

a) import JOptionPane
b) using JOptionPane
c) include JOptionPane
d) import javax.swing.JOptionPane

Answer 1

The correct way to make the JOptionPane class available in a Java program is by using the import statement 'import javax.swing.JOptionPane'. This should be placed at the beginning of the Java source file, allowing the programmer to use JOptionPane classes within their program. Option number d is correct.

Step-by-step explanation:

The correct answer to the question is d) import javax.swing.JOptionPane. This statement is used in Java to tell the compiler that your program will be using the JOptionPane class, which is part of the javax.swing package. Import statements are essential in Java programming because they inform the compiler about which packages and classes are needed for the program to work properly.

For example, if you want to use JOptionPane for showing a dialog box with a message, you would first need to import it at the beginning of your Java program as such: import javax.swing.JOptionPane; After this import statement, you can then use the JOptionPane class to create dialog boxes in your Java application.
