How do you write a deconstructor in Java?

Question

I came across this question and am looking for some ideas?

Answer 1

Try-with-resources is available as of Java 1.7

Anything that inherits from Closeable or Autocloseable can use it.

https://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html

try (FileReader br = new FileReader(path)) {
    return br.readLine();
}

This will automatically call a close function which is guaranteed to be called at the end of the block.
