El Ikhithi yoPhuhliso lweJava SE (JDK) yiphakheji yesoftware esisiseko kuye nawuphi na umphuhlisi weJava. Le phakheji iqulethe yonke into oyifunayo ukuyila, ukulungisa iimpazamo, kunye nokusebenzisa usetyenziso lweJava. Ukusuka kwinguqulelo esemthethweni yeqonga leJava ukuya kwezona zixhobo ziphambili zophuhliso, i I-JDK ibonelela ngeseti epheleleyo yezibonelelo ukuze abadwelisi benkqubo bakwazi ukusebenza ngokufanelekileyo nangempumelelo. Kweli nqaku, siza kuphonononga ngokweenkcukacha imixholo yephakheji ye Ikhithi yoPhuhliso lweJava SE kwaye siya kuqaqambisa izixhobo kunye nezinto eziluncedo ezenza kube yimfuneko kuyo nayiphi na iprojekthi yophuhliso lweJava.

– Inyathelo nenyathelo ➡️ Uthini umxholo wephakheji ye-Java SE Development Kit?

Yintoni umxholo wephakheji yeJava SE Development Kit?

  • Iphakheji ye-Java SE Development Kit (JDK) ibandakanya:
    • Java Runtime Environment (JRE): Kuyafuneka ukwenza usetyenziso lweJava kwikhompyuter yakho.
    • Javac: Ngumqokeleli weJava oguqula ikhowudi yomthombo weJava kwi-bytecode.
    • isixhobo seJava Archive (JAR): ikuvumela ukuba upakishe iifayile kwifomati yeJAR, ezizifayile zeZIP ezinolwazi lwemetadata.
    • Debugger: isixhobo esiluncedo ukulungisa ikhowudi yeJava.
    • JavaDoc: isixhobo sokwenza uxwebhu olusuka kwikhowudi yemvelaphi yeJava.
    • Ulawulo lweMishini yeJava: isixhobo sokuhlalutya kunye nokubeka iliso kwizicelo zeJava.
