Suppose we have a class:
public class Foo {
public void first() { print("first"); }
public void second() { print("second"); }
public void third() { print("third"); }
}
The same instance of Foo will be passed to three different threads.
Thread A will call first(), thread B will call second(), and thread C will call third().
Design a mechanism and modify the program to ensure that:
first is printed first.
second is printed second.
third is printed third.
Download and import the attached project.
You must use Semaphores and you can only modify theFooclass!

// 1 Complete the run method
// 2 complete the private boolean isPaladrome(long number)
// In Main
// 3 Create 4 FindPalindrome objects
// first should look like this
// FindPalindrome fp = new FindPalindrome((n)-> print(n),start, end);
// make start = end + 1
// and end = end XXXXXXXXXXfor each new FindPalindrome
// 4 Create 4 threads with the FindPalindrome
// 5 Start the threads
// What's wrong?
// Fix it!
