JAVA FEATURES 2019
New refactor feature
Checkstzle support
4
NEW REFRACTOR

• Refactoring is the one type of the process which
  changes only the structure of the existing
  program without affecting its functionality and
  usages.
• Refactoring is also improving the code
  reusability, performance and remove duplicate
  functionality and also remove the functionality
  which is not used.
• SYNTAX- Trigger rename after extract to
  variable/constant/method
• Here you can take the special rename action.
  And use the meaningful name. See in this image.

PROCESS OF REFACTORING
Detect Problem
Characterize the Problem
Design Solution
Modify the code
Is there problem or not?
What is the change necessary? and whats the
benefit after the changes?
What should Goal state code?
Carry out the Code transformations and leave the
code functioning as same the before.
And if the problem then check whats the problem.
Which code transformations will move towards?
Check that there are the any risks?

CHANGE IN XAMPLES
Rename
Move Class
Extract Method
Extract Super class
Replace Conditional with Polymorphism

EXTRACT TO FIELD

• The main reason for the use Extract variables is
  to make a complex expression is more
  understandable.
• The Extract Method refactoring lets you use a
  code fragment.
• That can be arranged, separate method and also
  old code with a call to the method.
• There are use the several time extract method in
  the same place.
• When you use Extract method there are you need to
  check for variables.
• One output variable can be used as a return value
  for the extracted method.
• Multiple output variables the extract methods
  refactoring may not be applied and the error
  message resembles.

  selection.
• We have achieved the smart select API used with
  the Expand Selection (ShiftAltRight) and Shrink

• Maven was released in 2004.
• It has raised a few of the problem of ANT.

  different version of the same library.
• And other draw back is that customization of the
  goal is too much hard.

11
GRADLE PREFERENCES

• Gradle was released in 2012.
• Google adopted the Gradle as a default build tool
  for the Android.
• Maven use the XML where as Gradle does not use
  the XML.
• It has own DSL based on JVM languages.
• Gradle used Apache lvy for its dependency
  management.

• Check style is Java web development tool and it
  helps to programmers write java code.
• It has the main features is that checkstyle can
  check the many aspects of your source code.
• Standard checkstyle are applicable to general

  libraries.

14
CONCLUSION

• So here present the features of the Java
  Development in 2019.
• Day by day java is also released new features and
  versions also.
• It make more simple and fulfill all the
  requirements of the developers.
• And developers have always updated with the java.
