If multiple resources are acquired, the correct way to deal with them is with nested try blocks.<ref>Bloch, Joshua (2018). ''Effective Java, Third Edition''. Addison-Wesley. Item 9, p. 54. {{ISBN|978-0-13-468599-1}}</ref> For this reason and others, ''try-with-resources'' was added to the language to almost entirely replace finally clauses. Resources acquired in a parentheses after the try keyword will be cleaned up automatically. Classes used in these statements must implement an interface called AutoCloseable.<ref>{{cite web | url=https://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html | title=The try-with-resources Statement (The Java™ Tutorials > Essential Java Classes > Exceptions) }}</ref>
