The document discusses the challenges associated with boilerplate code in the industry, including syntax verbosity and non-standardization, highlighting human errors and the repetitive nature of defining getters and setters. It introduces Project Lombok, which simplifies code through annotations such as @getter, @setter, and @data, enabling automatic generation of methods and constructors. Additional features like @cleanup for resource management and various logger options are also covered, with more information available through the project's website.

2. Problems of the Industry
Boiler Plate Code
Syntax Verbosity
Non Standardization
Not following the standard code conventions!!
Human Error/Dependency
Repeatable things (defining Getters, Setters etc.)

3. Demo Video
Taken from http://projectlombok.org/
Gives an idea what Project Lombok is and how it
can be installed.
Simple Demo of few Features.

4. Features
@Getter, @Setter, @ToString, @EqualsAndHashCode, @Data
@NoArgsConstructor, @RequiredArgsConstructor and
@AllArgsConstructor
@Cleanup, @Synchronized
@Log
@Delegate
val

5. @Getter and @Setter
Automatic Generation of getters and setters.
Method will be public unless you explicitly specify an
AccessLevel
@Getter and/or @Setter annotation on class
Disable getter/setter generation for any field by using
the special AccessLevel.NONE
@NotNull for nullity check
Demo

6. @ToString
Generates a default implementation of the toString()
method
Parameters 
Demo

7. @EqualsAndHashCode
Generates hashCode and equals implementations from
the fields (non-static, non-transient)
Parameters 
Demo

8. Constructor level Annotations
@NoArgsConstructor, @RequiredArgsConstructor, @AllA
rgsConstructor
Generates constructors that take no arguments, one
argument per final / non-null field, or one argument for
every field.
Specialized constructor can be made. Compile-time error
in case of any conflicts.
Demo

9. @Data
All together now: A shortcut for
@ToString, @EqualsAndHashCode, @Getter on all
fields, @Setter on all non-final fields, and
@RequiredArgsConstructor
Included annotations with changed parameters can be
defined along with @Data

10. @Cleanup
Automatic resource management: Call your close() methods
safely with no hassle.
Example: @Cleanup InputStream in = new
FileInputStream("some/file");
If the type of object you'd like to cleanup does not have a
close() method, but some other no-argument method like
dispose() so write it as
@Cleanup("dispose") TestClass t = new TestClass();

11. Logger Annotations!
Generate a logger field with name “log”
Four options
@CommonsLog
@Log
@Log4j
@Slf4j

12. And Lot More!!!
Some other supported features like
@Delegate, @Synchronized, val etc.
More to come soon!
