Infix notation and Live templates

IntelliJ lets you complete code statements in several different ways.

1. Infix notation.

1. To create a loop that goes over each variable, try typing the variable name, a .fori. It should expand into a for loop that creates an index.
2. To create a loop that creates a foreach, type the variable name and then a .for. It will expand into a foreach loop.

2. Live templates. Look at Settings -> Live templates.

3. With these, you can ifn or ifnn and a tab to get if null or if not null constructs.
4. You can also construct your own.

1. I added a logging category and set logdecl to private final org.slf4j.Logger log = org.slf4j.LoggerFactory.getLogger(this.getClass());, as I had done before, in Eclipse.
2. You can also add variables. I set logstart to be log.info("Entering $METHOD$.");. Then I pressed the Edit Variable button and told it that the expression to use was a predefined methodName().
