Q: run this code in NetBeans and give me the modification and output

package sdh; import java.util.concurrent.Semaphore; public class Sdh { private Semaphore s; // Semaphore to control access to the database private int r; // Count of the number of readers currently accessing the database private int data; // The shared data in the database public Sdh() { this.s = new Semaphore(1); this.r = 0; } public int readData() throws InterruptedException { s.acquire(); // Acquire the semaphore r++; // Increment the number of readers if (r == 1) { // If this is the first reader, acquire the semaphore again to prevent writers from accessing s.acquire(); } s.release(); // Release the semaphore int readData = data; // Read the data s.acquire(); // Acquire the semaphore r--; // Decrement the number of readers if (r == 0) { // If this is the last reader, release the semaphore to allow writers to access s.release(); } s.release(); // Release the semaphore return readData; // Return the read data } public void writeData(int data) throws InterruptedException { // Acquire the semaphore to prevent readers and other writers from accessing s.acquire(); // Write the data this.data = data; // Release the semaphore to allow readers and other writers to access s.release(); } public static void main(String[] args) { Sdh sharedDatabase = new Sdh(); try { sharedDatabase.writeData(5); int readData = sharedDatabase.readData(); System.out.println("Read data: " + readData); } catch (InterruptedException e) { e.printStackTrace(); } } }
