One extremely common task that occurs when writing JavaSW applications is to catch exceptions via a try/catch block. EclipseSW can automatically generate a try/catch block for you. As an example, below we have an instantiation of a FileWriter object, which throws an IOException.

Unhandled exception

Let's automatically generate a try/catch block to handle this exception. To do so, I highlight the code that I'd like to surround with the try/catch block. I then right-click and select Surround With → Try/catch Block.

Surround with try/catch block

This automatically generates a try/catch block, as shown below. The IOException is automatically imported, and the catch block outputs the stack trace to standard error via e.printStackTrace().

This is one of the Eclipse tools that I consider essential.
