Cov kauj ruam
Kauj Ruam 1. Txheeb xyuas seb koj li Ubuntu Linux operating system architecture yog 32-ntsis lossis 64-ntsis, qhib lub davhlau ya nyob twg thiab khiav cov lus txib hauv qab no
-
Hom/Luam/Muab Tshuaj:
cov ntaub ntawv /sbin /init
Nco tseg me ntsis version ntawm koj Ubuntu Linux kev ua haujlwm tsim qauv nws yuav tso saib seb nws yog 32-ntsis lossis 64-ntsis
Kauj Ruam 2. Txheeb xyuas yog tias koj muaj Java teeb tsa ntawm koj lub kaw lus
Txhawm rau ua qhov no, koj yuav tsum tau khiav Java version hais kom ua los ntawm davhlau ya nyob twg.
-
Qhib lub davhlau ya nyob twg thiab nkag mus rau cov lus txib hauv qab no:
-
Hom/Luam/Muab Tshuaj:
java -version
-
