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-null field, 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?"Configuration systemLombok, made to order: Configure lombok features in one place for your entire project or even your workspace.Experimental featuresHere be dragons: Extra features which aren't quite ready for prime time yet.
