Siqala ngokwenziwa ngokwezifiso kofakelo lwethu olutsha lwe-Ubuntu 18.10 Yeyona nguqulelo yamvanje ukuza kuthi ga ngoku kwaye ikhutshwe kwiintsuku ezimbalwa ezidlulileyo.

Omnye Enye yezinto ekufuneka siyenzile phantse kwangoko kukudibanisa inkxaso yeJava kwinkqubo kuba uninzi lwezicelo esinokuzifumana kwiLinux ziyayifuna.

Java ngaphandle kwamathandabuzo lulwimi lwenkqubo esetyenziselwa iinjongo ezahlukeneyo kwaye yinto ebaluleke kakhulu ekuphumezeni nasekusebenziseni izixhobo ezahlukeneyo, Ukufakwa kweJava kungumsebenzi obalulekileyo emva kokuba wenze ufakelo lweJava.

Yiyo loo nto Ngeli xesha ndiza kwabelana nawe ngesifundo esilula sendlela yokufaka iJava kwinkqubo yethu.

I-OpenJDK luhlobo oluvulekileyo loluntu lweJava. Isetyenziswa ngokubanzi kuba ifumaneka ngokungagqibekanga ku-Ubuntu kunye nolwabiwo oluninzi lweLinux.

Nangona kunjalo, ayinakusetyenziselwa ukuphuhlisa usetyenziso lwentengiso. IJava lulwimi olujolise kwinto eneOracle. Lulwimi oluhlanganisiweyo, olunemithetho yalo nolusasazwa ngokubanzi kumanqanaba emfundo kunye nobungcali.

Malunga ne-Oracle Java

Yenziwe ngamacandelo amathathu asisiseko: i-JDK, JRE, kunye ne-JVM.

I-JDK yikhithi yophuhliso lweJava Umqulathi oqukethe kunye neelayibrari ezifunekayo ukuqala ukwakha izicelo ngeJava.

El Indawo yokusiNgqongileyo yeJava (JRE) yindlela yokuqhuba ezi zicelo.

Ekugqibeleni, umatshini weJava (JVM) isebenza njengomaleko ophakathi phakathi kweJRE kunye nenkqubo yokusebenza kwezicelo zeJava ezisebenzayo.

IJava iyahambelana neLinux, oku kuthetha ukuba kunokwenzeka ukuqhuba kunye nokwakha usetyenziso kulwabiwo lwakho oluthandayo.

Ingxaki yile Inguqulelo kwizinto zokugcina ezisemthethweni isekwe kwi-OpenJDK. Ngamafutshane, oku kuthetha ukuba asinakho ukuyisebenzisa ukwenza usetyenziso lwentengiso, ukongeza ekubeni luhlobo loluntu olunenzuzo kunye nezinto ezingalunganga ezinokuthi zibonakalise.

Ngoko ke, Ukuba ufuna ukuphuhlisa usetyenziso lomntu wesithathu ngaphandle kweengxaki zelayisensi, ukhetho lwakho kukufaka iJava kwiOracle.

Njengoko bekutshiwo ngaphambili, ukufaka i-Oracle Java kubalulekile ukuba ungumphuhlisi. Ngethamsanqa, kunokwenzeka ukuba ukwenze ngokulula oku, enkosi kwindawo ekuphakanyiswa kuyo iPPA yeJava.

Le ndawo yokugcina izinto ilungiselela inkqubo yokukhuphela, ukufaka, kunye nokumisela i-Oracle Java njengephakheji ye .deb.

Uyifaka njani i-Oracle Java 11 kwi-Ubuntu 18.10 kunye neziphumo zayo?

IJava-11

Ukufaka i-Oracle Java 11 kwi-Ubuntu 18.10 kunye nezinto eziphuma kuyo kwaye sibe nakho ukufumana ngokuzenzekelayo uhlaziyo lwamva kuyo, kufuneka senze oku kulandelayo:

Masivule i-terminal yenkqubo, ungasebenzisa amaqhosha e-CTRL + ALT + T njengendlela emfutshane kwaye kwisiphelo sendlela siza kuchwetheza lo myalelo ulandelayo ukongeza indawo yokugcina kwinkqubo:

sudo add-apt-repository ppa:linuxuprising/java

Yenza le nto Kuya kufuneka sihlaziye iifasta kunye neephakeji ngomyalelo:

sudo apt-get update

Okokugqibela sinokuqhubeka ukufaka iJava nge:

sudo apt install oracle-java11-installer

Ukuchaza i-Oracle Java 11 ngokungagqibekanga (okanye hayi)

Indawo yokugcina izisa isixhobo isasazwa njengephakheji Iluncedo kakhulu ekuchazeni i-Oracle Java 11 njengohlobo oluqhelekileyo lweJava yenkqubo.

I-Oracle-java11-set-default package yafakwa njengephakheji ekhuthazwayo kufakelo lwe-Oracle-java11-installer kwaye awudingi kwenza enye into ngaphandle kokuqinisekisa ufakelo.

java --version

Kwelinye icala, sNdifuna ukufaka iJava 11, kodwa hayi umgangatho. Ke kuya kufuneka ususe i-Oracle-java11-set-default package.

sudo apt remove oracle-java11-set-default

Uyikhupha njani i-Oracle Java 11 kwi-Ubuntu 18.10 kunye neziphumo?

Ukuba ufuna ukususa le phakheji kwinkqubo yakho ngenxa yokuba ibingeyiyo le nto ubuyilindele okanye nangasiphi na isizathu, kufuneka silandele la manyathelo angezantsi.

Kuqala siza kususa indawo yokugcina evela kwinkqubo ngokuvula i-terminal kwaye kuyo siza kwenza lo myalelo ulandelayo

sudo add-apt-repository ppa:linuxuprising/java -r -y

Nje ukuba indawo yokugcina isuswe kwinkqubo, kufuneka sisuse yonke imikhondo yeJava kuyo, kuba oku siza kuchwetheza lo myalelo ulandelayo:

sudo apt remove oracle-java11-installer
