Java is a garbage collected language therefore you cannot predict when (or even if) an object will be destroyed. Hence there is no direct equivalent of a destructor.

There is an inherited method called finalize for Garbage Collection.

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.");

}
}
