Published on: May 15, 2025 | Source:Memory Leak Due to Time-Taking finalize() Method
All objects in Java implicitly inherit from java.lang.Object. This class contains multiple methods, which can be overridden in the child class. One such overridable method is finalize(). Before objects get garbage collected from memory, the JVM will execute the finalize(). So, if you need to close any resources that were opened in the class (like backend connections, Filesβ¦), it can be done in this method.
