Based on the given case, answer the following questions:
1. What issue did Aakash face while running his program?
a. The program didn't handle boundary conditions properly.
b. The program didn't assign a priority to high-priority tasks.
c. The program crashed when the user entered a time above 3 hours.
d. The program displayed "Low Priority" for all tasks.
2. What change should Aakash make to handle boundary values correctly for time required?
a. Change the condition timeRequired <= 1 to timeRequired < 1.
b. Modify the else if condition to use timeRequired >= 1 && timeRequired < 3.
c. Use a switch-case statement to classify tasks.
d. Modify the condition to check for exact hours only (i.e., 1 hour and 3 hours).
3. Which control statement did Aakash use to assign task priorities?
a. if-else-if statement b. for loop
c. switch-case statement d. while loop
4. What could Aakash do to make his program more flexible if additional priority categories are added in the future?
a. Use multiple if-else-if statements for each category.
b. Use a switch-case statement to handle different categories dynamically.
c. Use a loop to automatically assign priority.
d. Use a for loop to check for different time ranges.
F. Write the Java program for the following:
1. Write a program to compute the amount that customer pays for the taxi that he hires based on following conditions:
Distance Rate
Up to 5 km: `75
For the next 10 km: `15/km
For the next 20 km: `10/km
More than 25 km: `5/km
2. Write a program to display the following pattern using switch case.
i. 1
1 0
1 0 1
1 0 1 0
1 0 1 0 1
ii. 1 2 3 4 5
2 2 3 4 5
3 3 3 4 5
4 4 4 4 5
5 5 5 5 5
3. Write a program in Java to display all the prime Fibonacci series numbers upto n.
E.g., 2, 3, 5, 13, 233, etc.
G. Find the output of the following programs:
1. class Main {
public static void main(String[] args) {
for(int i=1; i<=10; i=i*2){
System.out.println(i);
}
}
}
