Limbajul a ap\u0103rut accidental <\/b><\/a>\u00een 1991<\/b> \u0219i a fost ini\u021bial destinat pentru televiziune interactiv\u0103. Trebuia s\u0103 fie limbajul pentru set-top box-uri \u0219i televizoare, dar a fost folosit \u00een schimb pentru programarea pe internet. Mai t\u00e2rziu, „scrie o dat\u0103, ruleaz\u0103 oriunde” a devenit celebra mantr\u0103 a creatorilor limbajului, iar originea popularit\u0103\u021bii Java este evident\u0103 \u00een aceast\u0103 zical\u0103. C\u00e2nd au \u00eenceput s\u0103 dezvolte limbajul \u00een anii ’90, dezvoltatorii de la Sun Microsystems s-au g\u00e2ndit la 5 obiective cheie, <\/b>care erau absolut revolu\u021bionare la acea vreme. Aceste aspecte au constituit apoi norma pentru at\u00e2t de multe limbaje de programare care au urmat:<\/p>\n

    \n
  1. de a adopta o abordare orientat\u0103 pe obiecte (mai multe despre acest aspect mai t\u00e2rziu)<\/li>\n
  2. de a permite mai multor sisteme de operare s\u0103 ruleze acela\u0219i program (de aici \u0219i mantra „scrie o dat\u0103, ruleaz\u0103 oriunde”)<\/i><\/li>\n
  3. de a avea un suport de re\u021bea de calculatoare \u00eencorporat<\/li>\n
  4. de a executa cod din surse \u00eendep\u0103rtate \u00een siguran\u021b\u0103<\/li>\n
  5. de a fi simplu de utilizat

    <\/li>\n<\/ol>\n

    Doar arunc\u00e2nd o privire la aceast\u0103 list\u0103, po\u021bi vedea c\u0103 s-au depus multe eforturi pentru a face Java c\u00e2t mai simplu \u0219i mai u\u0219or de utilizat. Aceasta se str\u0103duie\u0219te s\u0103 fie independent at\u00e2t de platforma, c\u00e2t \u0219i de sistemul de operare <\/b>pe care ruleaz\u0103. De asemenea, se pune un mare accent pe compatibilizarea codului cu sisteme \u0219i versiuni mai noi, f\u0103r\u0103 a fi nevoie de migr\u0103ri sau de extindere, pe care o numim „compatibilitate retroactiv\u0103<\/b>„. \u00cen plus, este un limbaj care evolueaz\u0103 <\/b>foarte rapid.<\/b> Apar noi ad\u0103ugiri \u0219i capabilit\u0103\u021bi pe m\u0103sur\u0103 ce se schimb\u0103 cerin\u021bele industriei \u0219i se produc progrese tehnologice.<\/p>\n

    Acestea sunt principalele caracteristici ale Java \u0219i, de asemenea, principalele motive care stau la baza popularit\u0103\u021bii sale de nezdruncinat. Dar trebuie s\u0103 observ\u0103m c\u0103 Java nu este doar un simplu limbaj de programare. Este un ecosistem de dezvoltare complex, <\/b>iar multe dintre cele mai mari organiza\u021bii din lume se bazeaz\u0103 pe el pentru proiectele \u0219i solu\u021biile lor.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    Java este:<\/p>\n

    – platforma de dezvoltare nr. 1\u00a0<\/b>din lume,<\/p>\n

    – utilizat\u0103 de\u00a0peste 10 milioane de dezvoltatori<\/b>,<\/p>\n

    –\u00a0alegerea nr. 1 a dezvoltatorilor pentru cloud\u00a0<\/b>computing.<\/p>\n

    Java este utilizat \u00een principal pentru a crea software \u0219i aplica\u021bii complexe, la scar\u0103 larg\u0103, care pot fi apoi distribuite pe un spectru vast. De exemplu, o mul\u021bime de b\u0103nci folosesc Java pentru aplica\u021biile \u0219i software-ul lor, deoarece Java are o reputa\u021bie \u00eendelungat\u0103 de a fi cel mai de \u00eencredere \u0219i cel mai sigur limbaj. A\u0219a c\u0103, \u00een mod natural, industriile care \u021bin la aceste calit\u0103\u021bi au \u00eenceput s\u0103 \u00eel foloseasc\u0103 rapid.<\/p>\n

    Ei bine, datorit\u0103 versatilit\u0103\u021bii \u0219i adaptabilit\u0103\u021bii sale, Java este coloana vertebral\u0103 a programelor de studii orientate pe obiecte din majoritatea \u0219colilor din \u00eentreaga lume. \u0218i la Codecool – Java este, de obicei, primul limbaj cu care studen\u021bii lucreaz\u0103 atunci c\u00e2nd \u00eencep s\u0103 abordeze OOP.<\/p>\n

    Dar ce este de fapt\u00a0programarea orientat\u0103 pe obiecte\u00a0<\/b>\u0219i de ce este\u00a0mai complex\u0103\u00a0<\/b>scrierea de coduri \u00een cadrul acesteia?<\/p>\n

    \u00cen prezent, acesta este practic standardul \u00een industria de programare. Pe scurt, conceptul const\u0103 \u00een faptul c\u0103 dorim s\u0103 cod\u0103m a\u0219a cum vedem lucrurile \u00een realitate – vedem obiecte \u00een jurul nostru, iar acestea se raporteaz\u0103 unele la altele \u0219i la lume \u00een at\u00e2t de multe moduri diferite. \u0218i vrem s\u0103 putem pune aceste rela\u021bii \u00een cod. Vrem s\u0103 putem codifica realitatea noastr\u0103.<\/p>\n

    Totu\u0219i,\u00a0limbajele orientate pe obiecte vin cu o ton\u0103 de cuvinte \u0219i concepte noi<\/b>, cum ar fi g\u00e2ndirea OO, \u00eencapsularea sau injec\u021bia de dependen\u021b\u0103. Din aceast\u0103 cauz\u0103, primul limbaj orientat pe obiecte pe care \u00eel \u00eent\u00e2lne\u0219ti poate p\u0103rea mult mai complicat dec\u00e2t este de fapt. Acesta ar putea fi motivul pentru care exist\u0103 at\u00e2ta mitologie \u00een jurul Java \u0219i at\u00e2t de multe discu\u021bii pe marginea acestuia – atunci c\u00e2nd studen\u021bii \u00eencep s\u0103 \u00eel \u00eenve\u021be \u0219i doar privesc codul pentru prima dat\u0103, poate fi pu\u021bin descurajant.

Acesta este unul dintre motivele pentru care vei \u00eencepe s\u0103 \u00eenve\u021bi Java abia \u00een cel de-al treilea modul al cursului nostru de full stack developer, numit modulul OOP,\u00a0dup\u0103 aproximativ 5-7 luni<\/b>.<\/p>\n

    \u00cen plus, acesta va fi momentul \u00een care cursan\u021bii Codecool se vor\u00a0apropia de standardele industriei,\u00a0<\/b>iar Java este modalitatea perfect\u0103 de a intra \u00een fluxul de\u00a0g\u00e2ndire orientat\u0103 pe obiecte<\/b>.

    La cursul nostru de full-stack developer, vei construi mai \u00eent\u00e2i baze solide \u00een aproximativ 6 luni (primele 2 module, ProgBasic \u0219i Web), care sunt necesare \u00eenainte de a \u00eencepe s\u0103 \u00eenve\u021bi OOP \u00een alte 3 luni, care vine la pachet cu Java. Iar \u00een ultimul modul de 3 luni al cursului de 1 an, \u00ee\u021bi po\u021bi alege propria specializare, de exemplu, aprofundarea cuno\u0219tin\u021belor despre Java \u0219i utilizarea bibliotecilor la un nivel mai avansat. La final, vei ob\u021bine cuno\u0219tin\u021be aprofundate pe care nu le vei ob\u021bine \u00eentr-un Bootcamp obi\u0219nuit. Pe l\u00e2ng\u0103 o \u00een\u021belegere aprofundat\u0103 \u0219i o rutin\u0103 \u00een lucrul cu Java, vei cunoa\u0219te \u0219i alte 3-5 limbaje de programare \u0219i o serie de tehnologii complementare.<\/p>\n
