Hi method,

finalize :

Every class inherits the finalize() method from java.lang.Object the method is called by the garbage collector when it
determines no more references to the object exist the Object finalize method performs no actions but it may
be overridden by any class normally it should be overridden to clean-up non-Java
resources ie closing a file if overridding finalize().

for example :

import java.io.*;
public class FinalizeObject extends FileOutputStream {

// Contructor definition of the FinalizeFileOutputStream class.
public FinalizeFileOutputStream() throws IOException{
super("Rose India"); // call the super class constructor.
}

public static void main(String[] args) throws IOException {

// Create object of FinalizeFileOutputStream class.
FinalizeFileOutputStream objOutstream = new FinalizeFileOutputStream();

// finalize() method call.
objOutstream.finalize();
System.out.print("Stream is closed successfully and connection has "+
"cleaned up to the file.");

}
}


Thanks
