Amfani da tallafin JDK - JRE (na asali da na kamfani) na iya ba mu a mafi yawan lokuta mafi daidaituwa, tallafi da sababbin ayyuka fiye da waɗanda OpenJDK da IcedTea suka bayar.

Lokacin da zaɓuɓɓukan aikinmu tare da waɗannan aikace-aikacen da muke da su a cikin tsari kyauta suka wuce, kuma muka yi la'akari da hakan gabaɗaya, ba a samun su a cikin rarrabawarmu ko ma'ajiyar da ke kwaikwayon sabon sigar JDK, yana da kyau sannan a yi shi da hannu ko ta hanyar Rubutu na Bash Shell ya ce shigarwa, wanda wani abu ne mai matukar amfani.

Saboda haka, ta amfani da Kit ɗin Ci gaban Java (Oracle JDK) wanda shine Akwatin Ci Gaban hukuma don yaren shirye-shiryen Java, muhallin ci gaban abu, yanada matukar amfani kuma ya zama dole.

Kuma me yasa za a sanya Java JDK?

Tuna baya post on JDK ciki da waje wannan rukunin yanar gizon zamu iya haɗawa game da JDK cewa wannan software ko aikace-aikacen yana bamu damar rubuta Java applets da aikace-aikace a ciki ko a waje na burauzar intanet.

JDK ya hada da Java Runtime Environment (JRE), Java Compiler, da Java APIs. Wanne yana da matukar amfani ga sababbin ƙwararrun masu shirye-shirye.

JDK ba lallai bane mafi yawan lokuta don mai amfani ko mai amfani na asali, wani lokacin kawai don abubuwa masu sauƙi kamar saka Wasannin Console na Yanar Gizo.

A gefe guda, don masu ci gaba ko masu amfani da gudanarwa ana amfani da shi sau da yawa don abubuwa kamar takaddun shaida na lantarki, saboda maɓallansa applet ne.

Saboda haka, sau da yawa yana da mahimmanci a girka shi idan ba ku son rasa ɓangare mai kyau na gidan yanar gizo. Wato, kodayake akwai shafukan yanar gizo da yawa waɗanda ke ƙunshe da ƙananan ɓangarorin JDK (maɓallan, menus) ko waɗanda ma an tsara su gaba ɗaya a cikin JDK.

Saboda haka, Java JDK ba zai iya ɓacewa daga Binciken Gidan Gidan Gidanku da Tsarin Aiki gaba ɗaya ba!

Matakan da suka gabata

Kafin shigar da JDK ta hanyar umarni, dole ne zazzage shi daga gidan yanar gizon Oracle, don haka zaka iya zuwa gareta ta amfani da injin binciken intanet da ka zaɓa ko mahaɗin mai zuwa: Oracle - JDK 10

Bayan an zazzage shi, ƙila ba za a iya taƙaitawa ba ko kwafa daga yanayin zane na mai amfani zuwa inda ya cancanta, amma kuma za mu aiwatar da waɗannan matakan daga na'urar wasan bidiyo.
