New/strange Java “try()” syntax?

Question

While messing around with the custom formatting options in Eclipse, in one of the sample pieces of code, I saw code as follows:

/**
 * \'try-with-resources\'
 */         


        

Answer 1

Those are changes introduced in JDK7.

First statement is a try-with-resources. I don't know exactly why they exist but exceptions are often caused by inputstreams etc, I guess it just improves readability. Edit: thanks to the other answerers, I read the javadoc and I now know that it will close all i/o streams that implement AutoCloseable, omitting the need for a finally block in a lot of situations

Second is a multi-catch, which is really handy when you have different exceptions that you handle in exactly the same way.
