Is try-with-resource not safe when declaring multiple effectively final resources?
Since Java 9 we can use effectively final variables in try-with-resources. The example below presents a situation where one of the resources initialization throws an exception. When I run this example, the only output I get is a RuntimeException, meaning that Resource1 was not closed. That was expected, since it wasn’t initialized in the try-with-resources. But, is this the expected
try-finally with close auto-refactoring to try-with-resources with codestyle/checkstyle
I am working on a codebase that has recently migrated from Java 6 to Java 7. I would like to replace constructions like this: Connection conn = null; try{ conn = new Connection(); … } catch(…
Is the close method on a try-with-resources idiom not called if a constructor throws an exception?
I have a base class Base and a child class Child which extends it. Base implements java.lang.AutoCloseable. Let’s suppose that the constructor for Child throws a Foo. Now consider Is the Base#close method called if the exception is thrown? It is not on my machine, but is this something that the JLS has standardised? Answer Yes, close won’t be called.
Why write Try-With-Resources without Catch or Finally?
Why write Try without a Catch or Finally as in the following example? Answer As explained above this is a feature in Java 7 and beyond. try with resources allows to skip writing the finally and closes all the resources being used in try-block itself. As stated in Docs Any object that implements java.lang.AutoCloseable, which includes all objects which implement
