Title: Few features which are known the Java Developer


1
2019 JAVA FETURES
2
IMFROMATION
  • Java is the programming language.
  • That is class-based and object-oriented.
  • Java is one type of the WORA ( Write once run
    anywhere).
  • Java is run on any platform with the help of the
    JVM (Java Virtual Machine).
  • Java uses the spring, blade as a backend
    platform.
  • Java is the very popular language and their
    popularity behind reason is the
    Platform-independent and java eliminates a lot of
    security issues.

Smart Selection/Semantic API support
Maven improvements
Extract to field
Gradle preferences
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.

5
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?
6
CHANGE IN XAMPLES
Rename
Move Class
Extract Method
Extract Super class
Replace Conditional with Polymorphism
7
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.

8
SMART / SEMANTIC SELECTION API SUPPORT
  • Semantic selection is also known as smart
    selection.
  • We have achieved the smart select API used with
    the Expand Selection (ShiftAltRight) and Shrink
    Selection (ShiftAltLeft) commands.
  • Here get the more information about that.
  • https//code.visualstudio.com/updates/v1_33_smart

MAVEN IMPROVEMENTS
  • Maven was released in 2004.
  • It has raised a few of the problem of ANT.
  • Maven is use the XML as the format write build
    script.
  • It has the drawback is that Dependencies
    management does not handle conflicts well between
    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.

13
CHECKSTZLE SUPPORT
  • 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
    java coding style and require no external
    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.
