Java Runtime Environment imafunika kugwiritsa ntchito Java applications mkati mwa Ubuntu.
Mwamwayi pankhani ya kukhazikitsa Minecraft pali phukusi lokhazikika limene limapangitsa kuti likhale lophweka mosavuta monga likuwonetseredwa ndi bukhuli.
Mapulogalamuwa amapereka njira yowonjezeramo ntchito pamodzi ndi zodalira zake zonse mu chidebe kotero kuti palibe zotsutsana ndi makalata ena ndipo ntchitoyi imakhala yotsimikizika kugwira ntchito.
Komabe pakanema phukusi sichipezeka kwa onse ntchito kotero muyenera kukhazikitsa Java version nokha.

Kodi Mungatani Kuti Mukhale ndi Oracle Java Runtime Environment (JRE) Kwa Ubuntu?
Pali mapulogalamu awiri a Java Runtime Environment omwe alipo. Oracle amamasulidwa ndi maofesiwa. Chida ichi sichipezeka kudzera mu "Ubuntu Software" chida chomwe chimagwiritsidwa ntchito popanga zofunikira mu Ubuntu.
Webusaiti ya Oracle sichiphatikizapo phukusi la Debian . Phukusi la Debian ndi extension ".deb" ili ndi mawonekedwe omwe ali ovuta kuika mkati mwa Ubuntu.
M'malo mwake muyenera kuyika phukusiyo mwa kuyika pa fayilo "tar". Fayilo ya "tar" kwenikweni ndi mndandanda wa maofesi omwe amasungidwa pansi pa dzina limodzi la mafayilo omwe akayika malo omwe mafayilo ali mu mafoda awo olondola.
Njira ina ya Java Runtime Environment ndi yotsegula njira yotsegula yotchedwa OpenJDK. Bukuli silingapezeke kudzera pa chida cha "Ubuntu Software" koma likupezeka kuchokera ku mzere wa malamulo pogwiritsira ntchito bwino.
Ngati mukufuna kupanga mapulogalamu a Java muyenera kukhazikitsa Java Development Kit (JDK) m'malo mwa Java Runtime Environment (JRE). Monga ndi Java Runtime Zomwe Java Development Kits zimapezeka ngati oracle phukusi kapena phukusi lotsegula.
Bukuli lidzakusonyezani momwe mungakhazikitsire Oracle Runtime ndi Development Kits komanso njira zina zowonekera.
Kuti muyambe kukhazikitsa buku lovomerezeka la Oracle kapena Java Runtime Environment pitani https://www.oracle.com/uk/java/index.html.
Mudzawona maulendo awiri alipo:
- Java For Developers
- Java Kwa Ogula
Pokhapokha ngati mukufuna kukhazikitsa Java applications muyenera kudumpha pa "Java For Consumers".
Mudzawona batani lalikulu lofiira lotchedwa "Free Java Download".

Mmene Mungakhalire Oracle Java Runtime Kwa Ubuntu
Tsamba lidzawoneka ndi maulendo 4 pa ilo:
- Linux RPM
- Linux
- Linux x64
- Linux x64 RPM
Maofesi a Linux RPM ndi Linux x64 RPM si a Ubuntu kotero mungathe kunyalanyaza maulumikizi awo.
Linux link ndi 32-bit Baibulo la Java Runtime ndi Linux x64 link ndi 64-bit Version ya Java Runtime.
Ngati muli ndi kompyuta 64-bit mungathe kuyika fayilo ya Linux x64 ndipo ngati muli ndi makompyuta 32-bit, mufunadi kuyika fayilo ya Linux.
Pambuyo pake fayiloyi ikutsegula mawindo otsegula . Njira yosavuta yotsegula mawindo otsegula mu Ubuntu ndi kukakamiza CTRL, ALT ndi T nthawi yomweyo.
