Sengiphetha, i-Java SE Development Kit (JDK) iyithuluzi okufanele libe nalo lonjiniyela abasebenza ne-Java. Inikeza inhlobonhlobo yokusebenza nezinsiza ezisiza inqubo yokuthuthukisa isicelo ngalolu limi. Kusukela ekudaleni nasekuhlanganiseni ikhodi kuye ekulungiseni amaphutha nasekusebenziseni izinhlelo, i-JDK inikeza wonke amathuluzi adingekayo ukuze kufezwe le misebenzi. indlela ephumelelayo.

Esinye sezici ezibaluleke kakhulu ze-JDK wukuguquguquka kwayo kanye nokuvumelana nezimo ezindaweni ezithuthukile ezihlukene. Ingasetshenziswa kokubili ezindaweni ezihlanganisiwe zokuthuthukiswa (ama-IDE) nasezindaweni ezilula, njengabahleli bombhalo. Ukwengeza, i-JDK iyahambisana nezinhlelo zokusebenza eziningi, okwenza ifinyeleleke kubabukeli abaningi bonjiniyela.

Okunye okugqamile kwe-Java SE Development Kit ingcebo yezinsiza nemibhalo etholakala kubathuthukisi. Ngezifundo eziku-inthanethi, izinkundla zezingxoxo kanye namabhulogi akhethekile, kuyenzeka ukuthi ufinyelele ulwazi olunhlobonhlobo nezeluleko ezisebenzayo ukuze uthole okuningi ku-JDK. Ukwengeza, kunezibonelo eziningi zamakhodi nezifanekiso ezenza kube lula ukufunda nokusebenzisa imisebenzi ethile.

Sithemba ukuthi le ndatshana ikukhanyisele ngokusebenziseka kwe-Java SE Development Kit (JDK) nokuthi ingabazuzisa kanjani onjiniyela kumaphrojekthi abo. Njengoba kushiwo ngenhla, i-JDK iyithuluzi elibalulekile lokusebenza ngolimi lohlelo lwe-Java, ihlinzeka ngenkundla eqinile nephelele yokuthuthukiswa kohlelo lokusebenza. Kusukela ekuhlanganiseni nasekupakisheni kuye ekulungiseni amaphutha nasekuqapheni ukusebenza, i-JDK inikezela ngezinhlobonhlobo zezici nokusebenza okusiza ukwenza lula kanye nokwenza lula inqubo yokuthuthukisa. Ukwengeza, ukuhambisana kwayo kwe-cross-platform kuqinisekisa ukuthi izinhlelo zokusebenza ezakhiwe nge-JDK zingasebenza ezinhlobonhlobo zamadivayisi nezinhlelo zokusebenza. Ngaphandle kokungabaza, i-JDK iyithuluzi eliyigugu lanoma yimuphi umthuthukisi we-Java ofuna ukwakha izinhlelo zokusebenza eziqinile, ezisebenza kahle kakhulu.
