Write a Java application that simulates a test. The test contains at least five questions about first three lectures of this course. Each question should be a multiple-choice question with 4 options.
Exercise 1:
Write a Java application that simulates a test. The test contains at least five questions about first three lectures of this course. Each question should be a multiple-choice question with 4 options.
Design a Test class. Use programmer-defined methods to implement your solution. For example:
- create a method to simulate the questions – simulateQuestion
- create a method to check the answer – checkAnswer
- create a method to display a random message for the user – generateMessage
- create a method to interact with the user - inputAnswer
Display the questions using methods of JOptionPane class. Use a loop to show all the questions.
For each question:
- If the user finds the right answer, display a random congratulatory message (“Excellent!”,”Good!”,”Keep up the good work!”, or “Nice work!”).
- If the user responds incorrectly, display an appropriate message and the correct answer (“No. Please try again”, “Wrong. Try once more”, “Don't give up!”, “No. Keep trying..”).
- Use random-number generation to choose a number from 1 to 4 that will be used to select an appropriate response to each answer.
- Use a switch statement to issue the responses, as in the following code:
switch ( randomObject.nextInt( 4 ) )
{
case 0:
return( "Very good!" );
……
}
At the end of the test display the number of correct and incorrect answers, and the percentage of the correct answers.
Your main class will simply create a Test object and start the test by calling inputAnswer method.
Exercise 2:
Write a Java class that implements a set of three overloaded static methods. The methods should have different set of parameters and perform similar functionalities. Call the methods within main method and display the results.
