Final answer:
The synchronization mechanism in Java is implemented using synchronized methods and synchronized blocks to ensure that only one thread can execute a method or block of code at a time, controlling access to shared resources and preventing concurrent issues.
Step-by-step explanation:
The synchronization mechanism in a Java environment is implemented using synchronized blocks or synchronized methods. When a method is declared with the synchronized keyword, it ensures that only one thread can access it at a time. Similarly, synchronized blocks can be used to protect a section of code by acquiring a lock on a given object, which restricts multiple threads from executing the code block concurrently.
To create a synchronized method, you simply add the synchronized keyword to the method's declaration. Here's an example:
public synchronized void synchronizedMethod() {
// method code here
}
For synchronized blocks, you specify the object that is being used as a lock:
synchronized(lockObject) {
// block of code to be synchronized
}
It's essential to use synchronization wisely to avoid issues like deadlocks or decreased performance due to excessive synchronization.
