When is the finalize() method called in Java?

In Java, the finalize method is called by the garbage collector when it determines that an object is no longer reachable.

The finalize method is a protected method defined in the Object class, and it can be overridden by subclasses to release resources or perform other cleanup tasks before an object is garbage collected.

Here's an example of how you can override the finalize method in a Java class:

public class MyClass {
  private Resource resource;

  public MyClass(Resource resource) {
    this.resource = resource;

  protected void finalize() throws Throwable {
    try {
    } finally {

This code defines a class MyClass with a field resource of type Resource. The finalize method is overridden to close the resource before the object is garbage collected.

It's important to note that the finalize method is not guaranteed to be called, as it depends on the garbage collector's implementation and the system's resources. It's also not recommended to rely on the finalize method for releasing resources, as it can have a negative impact on the performance of the garbage collector.

I hope this helps! Let me know if you have any questions.
