• Use if-else statement.
• Refer a segment of program given below along with screenshot of the
output:
// Question 1
System.out.println("Question 1: What does CPU stand for?");
System.out.println("A. Computer Processing Unit");
System.out.println("B. Central Personal Unit");
System.out.println("C. Central Processing Unit");
System.out.println("D. Central Processor Unit");
System.out.print("Your answer: ");
char answer1 = Character.toUpperCase(scanner.next().charAt(0));
if (answer1 == 'C') {
System.out.println("Correct!");
score++;
} else {
System.out.println("Incorrect. The correct answer is C.");

} else if (task2 == null) {
task2 = newTask;
} else if (task3 == null) {
task3 = newTask;
} else {
System.out.println("To-Do list is full! Complete or remove tasks before
adding more.");
}
break;
