Problems With Finalizer

In Java, the finalize method has been part of the language since its early days, offering a mechanism to perform cleanup activities before an object is garbage collected. However, using finalizers has come under scrutiny due to several performance-related concerns. As of Java 9, the finalize method has been deprecated, and its use is highly discouraged.

Delayed Garbage Collection

Finalizers can substantially slow down the garbage collection process. When an object is ready to be collected but has the finalize method, the garbage collector must call this method and then re-check the object in the next garbage collection cycle. This two-step process delays memory reclamation, leading to increased memory usage and potential memory leaks.
