Whether you're grappling with inheritance, polymorphism, or threading, our team of experts is equipped to guide you through every step of the way.

Master-Level Programming Questions: A Glimpse into Complexity

Let's dive into the heart of Java programming with master-level questions designed to test your skills and broaden your understanding. Our expert, armed with years of experience, presents solutions to these challenging problems, shedding light on intricate concepts.

Question 1: The Challenge of Multithreading

Consider a scenario where you need to implement a multithreading application to simulate a banking system with multiple transactions. Each transaction involves withdrawing or depositing funds from a shared account. Your task is to ensure thread safety and prevent race conditions.

import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

class BankAccount {
private double balance;
private final Lock lock = new ReentrantLock();

public BankAccount(double initialBalance) {
balance = initialBalance;
}

public void deposit(double amount) {
lock.lock();
try {
balance += amount;
} finally {
lock.unlock();
}
}

public void withdraw(double amount) {
lock.lock();
try {
balance -= amount;
} finally {
lock.unlock();
}
}

public double getBalance() {
return balance;
}
}

public class Transaction implements Runnable {
private BankAccount account;
private double amount;
private boolean isDeposit;

public Transaction(BankAccount account, double amount, boolean isDeposit) {
this.account = account;
this.amount = amount;
this.isDeposit = isDeposit;
}

public void run() {
if (isDeposit) {
account.deposit(amount);
} else {
account.withdraw(amount);
}
}
}

Solution:

In the given code, we ensure thread safety using a `ReentrantLock`. This lock allows only one thread to execute the critical sections of deposit and withdraw methods at a time, preventing race conditions and maintaining data integrity.

Question 2: The Conundrum of Recursive Algorithms

Now, let's explore a classic problem: implementing the Fibonacci sequence recursively. Your task is to write a Java program to compute the nth Fibonacci number efficiently.

public class Fibonacci {
public static int fibonacci(int n) {
if (n = 1)
return n;
return fibonacci(n - 1) + fibonacci(n - 2);
}

public static void main(String[] args) {
int n = 10;
System.out.println("Fibonacci sequence upto " + n + " terms:");
for (int i = 0; i n; i++) {
System.out.print(fibonacci(i) + " ");
}
}
}

Solution:

Although the above code computes Fibonacci numbers recursively, it suffers from exponential time complexity, making it inefficient for large values of n. To optimize the solution, we can utilize memoization to store previously computed values and avoid redundant calculations, resulting in improved performance.
