Annotation Type var

Use var as the type of any local variable declaration (even in a for statement), and the type will be inferred from the initializing expression (any further assignments to the variable are not involved in this type inference).

For example: var x = 10.0; will infer double, and var y = new ArrayList<String>(); will infer ArrayList<String>.

Note that this is an annotation type because var x = 10; will be desugared to @var int x = 10;

Complete documentation is found at the project lombok features page for @var.
