Java is the most popular programming language according to the TIOBE index. It remains widely used due to its many advantages, including being platform independent, having a mature and evolving design, rich APIs, and suitability for tasks like Android app development and embedded/IoT programming. Java sees ongoing support through new features and remains an important language for a variety of applications.

1. HelloEveryone!Doyouknowwhichone isthe mostpopularprogramminglanguage intoday's
world?
Yes,you are absolutelyright.Itis Java.
Accordingto TIOBE Index for2018, thistime too Javais ontop in the listof mostpopularand widely
usedprogramminglanguages world-wideincludingC,C++, C#, PythonandPHP. The statistics
uploadedonTIOBEitself depictsthe massivepopularityandsignificance of Javaintoday'sworld.
Java isan object-oriented,class-based,concurrent,securedandgeneral-purpose programming
language.Some developerspreferusingJavaforbuildingstand-alone applications,while others
developavarietyof webapplicationsbyleveragingJavatechnologies.Atthe same time,Javaisalso
usedwidelyfordevelopingmobileappsandgame forAndroid – the mobile platformwiththe largest
installedbase.
Java isnot onlya programminglanguage butithas become awell advancedrobusttechnologynow
and that iswhythere are a numberof reasonsforJava to remainimportantovera longerperiodof
time.
Reasons behind the popularity of Java Technology:-
1. Mature and keepsevolving
Java iscurrentlyone of the mature and stable programminglanguages.ButOracle Corporation
frequentlyupdatesthe programminglanguage withthe supportof avibrantcommunity.Eachnew
versionof Javacomeswithseveral newfeaturesandenhancedperformance.Forinstance,the latest
versionof Javasupportsbothfunctional andconcurrentprogramming.Also,itcomeswithseveral
newfeatureslike anewdate/timeAPIandimprovedNashornJVMJavaScriptengine,while
supportingparallel processingandlambdaexpressions.Thesenew featuresmake Java compete with
otherJVM-basedlanguagesmore efficiently.
2. PlatformIndependent
Before the evolutionof Java,Programmershadtowrite applicationsbytargetingmanydevicesand
platforms.Theywere lookingforaprogramminglanguage thatallowsthemtowrite code once and
deployonmultipleplatformswithoutputtingextraefforts. Now,programmerscaneasilycompile
theircode once intobyte-code andrunon multiple Javasupportedplatforms.
3. Common Programming Paradigm
The syntax of javais verymuch like of C and C++. Hence, programmers find easiertolearnand use
Java ina shorterperiodof time. Atthe same time,Javaisa concurrent,class-basedandobject-
orientedprogramminglanguage.AsJavasupportscommonobject-orientedprogramming(OOP)
conceptslike inheritance,polymorphism, abstractionandencapsulation,itbecomeseasierfor
programmersto make the applicationsmodular,extensible andscalable.Also,the developerscan
take advantage of certainJava librariestoimplementthe object-orienteddesignprinciplesmore
efficiently.

2. 4. Best for AndroidApp Development
While buildingmobile apps,nodeveloperscanignore Android –the mobile operatingsystemwith
the largestinstallationbase.The programmershave the optiontowrite AndroidappsinC,C++ or
Java.But Google recommendsmobile appdeveloperstowrite AndroidappsonlyinJava.The
developerscanfurtherboostthe application’sperformance andcompatibilityof the Androidapps
easilybywritingitinJava.The developersalsohave the optiontouse avarietyof toolsandlibraries
to write robustAndroidappsinJavawithina shorteramountof time.
5. Rich set ofAPIs
Java hasa rich setof applicationprogramminginterfaces(APIs). Usingthese APIs,programmerscan
easilyachieve theirdevelopmenttaskswithinashorterperiodof time withoutputtingextratime
and efforts.
6. Loads of Frameworks,Libraries, IDE and Developmenttools
The developershave optionstouse frameworks,libraries,IDE(NetBeans,MyEclipse,Eclipse etc.)
and several otherdevelopmenttools forJavatowrite readable andquality code withinshorter
periodof time withoutputtingtheirextraefforts.TheseIDEsimpartadvanceddebuggingcapabilities
and featurestoaccomplishtheirdevelopmenttasks.
7. Robust and Secured
The securityfeaturesprovidedbyJavamake iteasierforprogrammersto developlarge and
enterprise applications.The JavaVirtual Machine (JVM) evaluatesthe intermediate byte-code to
preventthe applicationfromperforming unsafe operations.The developerscanfurtheravail the
advancedsecuritymanagementfeaturesof Javato preventthe untrustedbyte-codefromaccessing
specificfeaturesandAPIs byrunningtheminasandboxedenvironment.Atthe same time,the
developers canalsoavail the robustsecurityAPIsprovidedbyJavaplatform, alongwithperforming
userauthenticationandusingsecure communicationprotocols,thatiswhy developertrustjava
more than otherlanguages.
8. FacilitatesEmbeddedComputing
Java wasoriginallydesignedforembeddedprogramming.ButmanydeveloperspreferCand Python
overJava while developingembeddedapplicationsforsystemswithconstrainedmemory.Theynow
have the optionto take advantage of the Java ME Platformtostandardruntime environmentfor
buildingavarietyof embeddedapplication.Inadditiontoincludingbuilt-innetworkprotocols,
robustsecurity,anda flexible userinterface,the microeditionof the JavaPlatformalsosupportsa
wide varietyof mobile andembeddeddevices.The applicationsdevelopedusingJavaME can run on
smartphones,tablets,sensors,gateways,printersandpersonal digital assistants(PDAs).These
featureswill encourage more developerstouse JavaME in future forembeddedcomputing.

3. 9. Supports for Internetof Things
Java isone of the programminglanguagesthatcurrentlysupportInternetof Things.The Project
Jigsawaimsto make the programminglanguage runona widervarietyof small andportable
devices.However,the projectstill aimstomaintainJava’sscalability,networking,maintainability,
security,performance andotherfeatureswhile makingitrunonsmallerandnewerdevices.Thatis
why;ProjectJigsawhasalreadyproposedadesignandstandardmodule systemforthe JavaSE
Platformtoaccomplishitsobjectives.Once the proposal isimplemented,programmerswill use Java
for writingawide varietyof Internetof Thingsapplications.
10. Simplifythe developmentofreal time software
Unlike conventional software applications, the real-time applicationsare requiredtodeliver
informationorresultswithinthe shortestamountof time.Atpresent,real-time software
applicationsare beingusedbymobiledevices,automobiles,medical devicesandfactories.Oracle
has includedseveral featuresinJavaSEto facilitate the developmentof real-time software.The APIs
providedbyJavaSE make it easierforprogrammerstoimplementthe real-time applications
smoothlyandeffectively.Manyprogrammerswilluse JavaSEin future fordevelopingreal-time
software thatiscompatible withvariousdevicesandplatforms,andcanbe integratedseamlessly
withthird-partycomponentsandapplications.
In a nutshell,aJava developercan use Java directlyfor writingdesktop GUIapplications,web
applicationsand mobile apps.The flexibilityandversatilitymake Java a general-purpose
programming language in the true sense.At the same time,the Java frameworksand
developmenttoolsalsocontribute hugelytowards making Java one of the most popular and
programming languagesof the year. That iswhy a lot of small businessownersalso use Java for
applicationdevelopment.These featureswill furtherkeepthe importance of Java intact overa
longerperiodof time.
