finalize()


It is a method present in a class which is called before any of its object is reclaimed by the garbage collector. Finalize() method is used for performing code clean-up before the object is reclaimed by the garbage collector.

Syntax:
public class MyClass
{
    protected void finalize()
    { 
        ... //code written here for clean-up

    }
}


Example:

import java.util.*;

public class ObjectDemo extends GregorianCalendar {

   public static void main(String[] args) {
      try {
         // create a new ObjectDemo object
         ObjectDemo cal = new ObjectDemo();

         // print current time
         System.out.println("" + cal.getTime());

         // finalize cal
         System.out.println("Finalizing...");
         cal.finalize();
         System.out.println("Finalized.");

      } catch (Throwable ex) {
         ex.printStackTrace();
      }


   }
}
