Lombok features.

val

Finally! Hassle-free final local variables.

@NonNull

or: How I learned to stop worrying and love the NullPointerException.

@Cleanup

Automatic resource management: Call your close() methods safely with no hassle.

@Getter/@Setter

Never write public int getFoo() {return foo;} again.

@ToString

No need to start a debugger to see your fields: Just let lombok generate a toString for you!

@EqualsAndHashCode

Equality made easy: Generates hashCode and equals implementations from the fields of your object..

@NoArgsConstructor, @RequiredArgsConstructor and @AllArgsConstructor

Constructors made to order: Generates constructors that take no arguments, one argument per final / non-nullfield, or one argument for every field.

@Data

All together now: A shortcut for @ToString, @EqualsAndHashCode, @Getter on all fields, and @Setter on all non-final fields, and @RequiredArgsConstructor!

@Value

Immutable classes made very easy.

@Builder

... and Bob's your uncle: No-hassle fancy-pants APIs for object creation!

@SneakyThrows

To boldly throw checked exceptions where no one has thrown them before!

@Synchronized

synchronized done right: Don't expose your locks.

@Getter(lazy=true)

Laziness is a virtue!

@Log

Captain's Log, stardate 24435.7: "What was that line again?"
