Is there a destructor for Java?

Java does not have a destructor like some other programming languages. In Java, objects are automatically garbage collected by the Java Virtual Machine (JVM) when they are no longer needed.

However, you can use the finalize() method of the Object class to specify code that should be executed just before an object is garbage collected. The finalize() method is called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

Here is an example of how you can override the finalize() method in a custom class:

public class MyClass {
  // instance variables and methods

  @Override
  protected void finalize() throws Throwable {
    try {
      // clean up code here
    } finally {
      super.finalize();
    }
  }
}

However, it is important to note that the finalize() method is not guaranteed to be called, and it is not recommended to rely on it for cleanup tasks. Instead, it is generally better to use try-with-resources or explicit resource management to ensure that resources are properly released.
