I-Java Runtime Environment iyadingeka ekusebenzeni izicelo zeJava ngaphakathi kwi-Ubuntu.
Ngenhlanhla xa kuziwa ekufakekeni kweMinecraft kukho iphakheji ye-snap ekhoyo eyenza ibe lula ngokulula njengoko kuboniswa kwesi sikhokelo.
I-Snap Iipakethi zinika indlela yokufaka isicelo kunye nazo zonke izixhomekeke kuzo kwisigubungelo ukuze kungabikho mpikiswano nezinye iilayibrari kwaye isicelo siqinisekisiwe ukuba sisebenze.
Nangona kunjalo iiphakheji ze-snap azikho kuzo zonke izicelo ukwenzela ukuba uzakufuneka ufake ifayile ye Java.

Indlela yokufumana i-Oracle Java Runtime Environment (Official) ye-Oracle Java (JRE) kwi-Ubuntu
Kukho iinguqulelo ezimbini ze-Java Runtime Environment ezikhoyo. I-version esemthethweni ikhutshwa yi-Oracle. Le nguqulo ayitholakali nge-"Ubuntu Software" ithuluzi elisetyenziswa ngokubanzi ekufakeni izicelo kwiBuntu.
I-website ye-Oracle ayibandakanyi iphakheji yakwaDebian. Iiphakheji zeDebian kunye ne ".deb" zandiswa ngendlela elula ukufaka kwiBuntu.
Kunoko kufuneka ufake iphakheji ngokufaka ngefayile "yentsimbi". Ifayile ye "tar" ngokuyinene uludwe lweefayile zonke ezigciniweyo phantsi kwelinye igama lefayile xa kufakelwe ukufaka ifayile kwiifolda ezichanekileyo.
Olunye uhlobo lwe-Java Runtime Environment lukhoyo luyimithombo evulekileyo ebizwa ngokuba yi-OpenJDK. Le nguqulo ayifumanekanga ngekhompyutha "Ubuntu Software" kodwa ifumaneka kumgca womyalelo usebenzisa i-access-get.
Ukuba uzimisele ukuphuhlisa iinkqubo zeJava uza kufuna ukufaka i-Java Development Kit (JDK) endaweni yeJava Runtime Environment (JRE). Njengoko kunye ne-Java Runtime Environments iikhompyutheni ze-Java zophuhliso ziyafumaneka njengepakethe ye-Oracle esemthethweni okanye ipakethe evulekile.
Esi sikhokelo siza kukubonisa indlela yokufaka zombini iiKhukhi ze-Oracle Runtime neNtuthuko ezisemthethweni kunye nezinye iindlela zokuvula.
Ukuqala ukufaka i-Oracle version okanye i-Java Runtime Environment vakashela i-https: //www.oracle.com/uk/java/index.html.
Uza kubona 2 izixhumanisi ezikhoyo:
- Java Kwabathuthuli
- Java KwaBathengi
Ngaphandle kokuba unenjongo yokuphuhlisa izicelo ze-Java kufuneka uqhosha kwikhonkco "yeJava kubaThengi".
Ngoku uza kubona iqhosha elikhulu elibomvu elibizwa ngokuba yi-"Free Java Download".

Indlela yokufaka i-Oracle Java Runtime For Ubuntu
Iphepha liza kubonakala nge-4 izixhumanisi kulo:
- RPM
- Linux
- Linux x64
- Linux x64 RPM
Iifayile ze-Linux RPM kunye ne-Linux x64 ze- RPM azikho kwi-Ubuntu ukuze unganakunyanisa ezo zixhumanisi.
Ikhonkco le Linux yinguqulo engama-32 ye-Java Runtime kunye nekhonkco ye Linux x64 yinguqulo engama-64 ye-Java Runtime.
Ukuba unekhompyutyana engama-64 uya kufuna ukufaka ifayile ye-Linux x64 kwaye ukuba unakho ikhompyutha ye-32-bit uyakufuna ukufaka ifayile ye-Linux.
Emva kwefayili efanelekileyo ikhupha ivula iwindow . Indlela elula yokuvula iwindi yokugcina kwi-Ubuntu kukucinezela i-CTRL, i-ALT kunye ne-T ngexesha elinye.
Into yokuqala yokuyenza kukufumana igama lefayile yangempela ekhutshwe kwiwebhusayithi ye-Oracle. Ukwenza oku kuqhuba le miyalelo elandelayo:
cd ~ / Downloads
ls jre *
Umyalelo wokuqala uya kutshintsha i-directory kwifayile yakho "Yokulanda". Umyalelo wesibini unikezela uluhlu lwemibhalo yazo zonke iifayile eziqala nge "jre".
Ngoku kufuneka ufunde igama lefayile likhangele into enje:
jre-8u121-linux-x64.tar.gz
Thatha igama lefayile okanye ukhethe nge mouse, nqakraza ngakwesokudla uze ukhethe ikopi.
Isinyathelo esilandelayo kukuba uhambe kwindawo apho uceba ukuyifaka iJava uze ukhiphe ifayile efakwe kwi-tar.
Qalisa le miyalelo elandelayo:
sudo mkdir / usr / java
cd / usr / java
sudo tar zxvf ~ / Downloads / jre-8u121-linux-x64.tar.gz
Iifayile ziya kukhishwa kwi-folder ye-usr / java kwaye yile nto.
Ukususa ifayile ekhutshweyo isebenze umyalelo olandelayo:
sudo rm ~ / Downloads / jre-8u121-linux-x64.tar.gz
Isinyathelo sokugqibela ukuhlaziya ifayile yakho yendawo ukuze ikhompyutha yakho ikwazi ukuba iJava ifakiwe kwaye yiphi ifolda yiJAVA_HOME.
Qalisa umyalelo olandelayo ukuvula ifayile yemo engqongileyo kwi-nano editor:
sudo nano / etc / indawo
Skrolela ekupheleni komgca oqala PATH = nangaphambi kokugqibela "faka oku kulandelayo
: /usr/java/jre1.8.0_121/bin
Bese ukongeza umgca olandelayo:
JAVA_HOME = "/ usr / java / jre1.8.0_121"
Gcina ifayile ngokucinezela i-CTRL kunye ne-O kwaye uphume umhleli ngokucindezela i-CTRL ne-X.
Unokuvavanya ukuba ngaba i Java isebenza ngokuthayipha umyalelo olandelayo:
java -version
Kufuneka ubone ezi ziphumo:
I-Java Version 1.8.0_121

Indlela yokufaka i-Oracle Java Development Kit ye-Ubuntu
Ukuba uceba ukuphuhlisa isofthiwe usebenzisa i Java ungafaka i-Java Development Kit esikhundleni se-Java Runtime Environment.
Jonga i-https: //www.oracle.com/uk/java/index.html kwaye ukhethe inketho "I-Java Kwabalimi".
Uza kubona iphepha elidibanisayo kunye nezonxibelelwano ezininzi. Khangela ikhonkco ebizwa ngokuthi "Java SE" eyokuthatha kule khasi.
Kukho ukhetho olungaphezulu kwezi-2:
- Faka Java JDK
- Faka iNetbeans
I-Java JDK ifaka kuphela i-Java Development Kit. Inketho ye-Netbeans ifaka indawo yokudibanisa okupheleleyo kunye ne-Java Development Kit.
Ukuba ucofa kwi-Java JDK uza kubona iinqununu. Njengoko kunye nexesha lokugijima uza kufuna ifayela le-Linux x86 ye-32-bit version ye-kit yokuphuhlisa okanye ifayili ye-Linux x64 ye-64-bit version. Awufuni ukucofa kwiinkcukacha ze-RPM, kunoko cofa kwikhonkco eliphela "kwi- tar.gz ".
Njengoko nge-Java Runtime Environment uza kuvula ukuvula ifowuni kwaye ufune ifayile oyilandileyo.
Ukwenza oku kuqhuba le miyalelo elandelayo:
cd ~ / Downloads
ls jdk *
Umyalelo wokuqala uya kutshintsha i-directory kwifayile yakho "Yokulanda". Umyalelo wesibini unikeza uluhlu lwemibhalo lwazo zonke iifayile eziqala nge "jdk".
Ngoku kufuneka ufunde igama lefayile likhangele into enje:
jdk-8u121-linux-x64.tar.gz
Thatha igama lefayile okanye ukhethe nge mouse, nqakraza ngakwesokudla uze ukhethe ikopi.
Isinyathelo esilandelayo kukuba uhambe kwiindawo apho uceba ukufaka itekiti yokuphuhlisa kwaye ukhiphe ifayile efakwe kwi-tar.
Qalisa le miyalelo elandelayo:
sudo mkdir / usr / jdk
cd / usr / jdk
sudo tar zxvf ~ / Ukulanda / jdk-8u121-linux-x64.tar.gz
Iifayile ziya kukhishwa kwi-folder ye-usr / java kwaye yile nto.
Ukususa ifayile ekhutshweyo isebenze umyalelo olandelayo:
sudo rm ~ / Downloads / jdk-8u121-linux-x64.tar.gz
Isinyathelo sokugqibela njengendawo yokusebenza ngexesha lokuqalisa ukuhlaziya ifayile yakho yendawo ukuze ikhomputha yakho ikwazi ukuba iJDK ifakiwe kwaye yiphi ifolda yiJAVA_HOME.
Qalisa umyalelo olandelayo ukuvula ifayile yemo engqongileyo kwi -nano editor :
sudo nano / etc / indawo
Skrolela ekupheleni komgca oqala PATH = nangaphambi kokugqibela "faka oku kulandelayo
: /usr/jdk/jdk1.8.0_121/bin
Bese ukongeza umgca olandelayo:
JAVA_HOME = "/ usr / jdk / jdk1.8.0_121"
Gcina ifayile ngokucinezela i-CTRL kunye ne-O kwaye uphume umhleli ngokucindezela i-CTRL ne-X.
Unokuvavanya ukuba ngaba i Java isebenza ngokuthayipha umyalelo olandelayo:
java -version
Kufuneka ubone ezi ziphumo:
I-Java Version 1.8.0_121

Enye indlela yokufaka i-Oracle Version ye-Java kwi-Ubuntu
Ukuba ukusetyenziswa kwe-Linux terminal kuyinto ongekho nto kunye nawe unokusebenzisa izixhobo zokubonisa ukufaka ifayile esemthethweni yeeKhaksi ze-Java Runtime Environment and Development.
Oku kufuna ukongeza i-archive yangaphandle yomqulu (PPA). I- PPA yindawo yokugcina yangaphandle engenakunikwa ngu-Canonical okanye Ubuntu.
Isinyathelo sokuqala ukufaka isiqwenga sesofthiwe esibizwa ngokuthi "Synaptic". I-Synaptic ngumphathi wephakheji yemifanekiso . Ihluke kwi-"Ubuntu Software" ithuluzi ekubuyiseni zonke iziphumo ezikhoyo kwiifayili zakho zeekhompyutha.
Ngelishwa ukuze ufake iSinaptic kufuneka usebenzise i-terminal kodwa umyalelo owodwa nje. Vula isigxina ngokucinezela i-CTRL, ALT kunye no-T ngexesha elinye.
Faka umyalelo olandelayo:
sudo apt-get install synaptic
Ukuqalisa iqhosha le-Synaptic kwi icon kwi-bar ye-launch kwaye uthayiphe i- "Synaptic". Xa uphawu lubonakala qhosha kuso.
Cofa kwi "Izicwangciso" imenyu uze ukhethe "Iifomathi".
Ikhutshana "Iprojekthi ye-Software ne-Updates" iya kuvela.
Cofa kwithebhu ebizwa ngokuba "enye iSoftware".
Cofa kwi "Yongeza" iqhosha uze ufake ezi zilandelayo kwifestile ebonakalayo:
ppa: webupd8team / java
Cofa kwiqhosha elithi "Vala".
I-Synaptic iya kucela ukuphinda ilayishe iifowuni ukuba idibanise uluhlu lwezihloko ze-software ezivela kwi-PPA oye wongeza.
05 ka 06
Faka i-Oracle JRE kunye ne-JDK usebenzisa i-Synaptic
Ngoku ungaphangela i-Oracle Java Runtime Environment kunye neJava Development Kits usebenzisa i-Synaptic.
Cofa kwiqhosha "Khangela" uze ufake "I-Oracle" kwibhokisi. Cofa iqhosha le "Khangela".
Uludwe lweephakheji ezikhoyo kunye negama elithi "Oracle" liya kuvela.
Ngoku unokukhetha ukuba ungayifaka indawo yendawo yokusebenza okanye ikethi yophuhliso. Akukuphela nje ukuba unokukhetha ukuba iyiphi inguqu yokufaka.
Okwangoku kunokwenzeka ukufakela kude emva kwe-Oracle 6 kude kube entsha ye-Oracle 9 engakhishwa ngokupheleleyo. I-version ephakanyisiweyo yi-Oracle 8.
Ukufaka ngokuqinisekileyo indawo yokupakisha isheke kwibhokisi elingaphandle kwento ofuna ukuyifaka kwaye nqakraza iqhosha elithi "Faka isicelo".
Ngexesha lofakelo uya kucelwa ukuba wamukele ilayisensi ye-Oracle.
Le nto yindlela elula ngakumbi yokufaka i-Oracle kodwa isebenzisa umntu we-PPA wesithathu kwaye akukho nto iqinisekisa ukuba oku kuza kube yinto ekhoyo.

Indlela yokufaka i-Open Source Java Runtime kunye neJava Development Kit
Ukuba ukhetha ukusebenzisa kuphela isofthiwe yomthombo ovulekileyo ke unako ukufaka iinguqulelo ezivulelekileyo zenguqu ze-Java Runtime neNtuthuko.
Uya kufuneka ufake iSinaptic ukuze uqhubeke kwaye ukuba awuzange ulifunde iphepha langaphambili indlela yokwenza oku ngale ndlela:
- Vula ifowuni yokuphela ngokucindezela i-CTRL, ALT kunye ne-T
- Faka umyalelo olandelayo kwi window window:
sudo apt-get install synaptic
Ukuqalisa iqhosha le-Synaptic kwi icon kwi-bar ye-launch kwaye uthayiphe i- "Synaptic". Xa uphawu lubonakala qhosha kuso.
Ngaphakathi kwe Synaptic konke okufuneka ukwenze kukucofa iqhosha elithi "Khangela" phezulu kwesikrini uze ufune "i-JRE".
Uluhlu lwezicelo luquka "I-default JRE" yenguqu evulekile yomthombo we-Java Runtime Environment okanye "OpenJDK".
Ukukhangela inguqu evulekile yomthombo we-Java Development Kit klikha kwi "Khangela" iqhosha uze ufune "i-JDK". Ukhetho olubizwa ngokuthi "OpenJDK JDK" luya kuvela.
Ukufakela indawo yepakethi ikiti kwibhokisi ecaleni kwento ofuna ukuyifaka kwaye cofa "Faka isicelo".
