Why do we use finalize() method in Java?

Comment

Java provides finalize() method to perform any cleanup before

Garbage Collection. This method is in Object class, and it is

invoked by JVM internally. Developers are free to implement this

method for any custom cleanup in case of Garbage Collection.

If an Object is not Garbage Collected, then this method may not be

called.

This method is never invoked more than once by JVM.

public class Data {

  public static void main(String[] args) {
    Data obj = new Data();
    obj = null;
    System.gc();
    System.out.println("Running garbage collector by gc() method");

    System.gc();
    System.out.println("Again try to run garbage collector by gc() method");
  }

  @Override
  // overriding method
  protected void finalize() {
    System.out.println("Finalize method is called");
  }
}
