Ngokuqinisekileyo, nantsi indlela eyakhiwe ngayo inqaku elide ngokwesicelo sakho.
Ukubonelela ngombono omfutshane kwingqikelelo ye-echo_home, oku kubhala kujolise ekucaciseni indlela echo_home kwi-Windows cmd. Inkqubo ye-echoing ekhaya ijikeleza ekuveliseni imveliso eqhele ukusetyenziselwa ukulungisa ingxaki enokuthi ibandakanywe nakwizikripthi ngokunjalo.
Ukusebenzisa i-echo_home kwiWindows CMD
I-Windows Command Prompt, eyaziwa ngokuba yi-cmd.exe okanye i-cmd, ibonelela abasebenzisi ngojongano lokusebenzisana nenkqubo yokusebenza ngemigca yomyalelo. Inika imiyalelo eyahlukeneyo kunye neempawu, kodwa esi sikhokelo sigxile ikakhulu kwi-echo_home kwi-Windows cmd.
Ukwenza isenzo se-echo_home, kufuneka uyimise. IWindows cmd ayinamsebenzi wasekhaya we-echo kanye njengeLinux. Endaweni yoko, sisebenzisa umyalelo othi "echo %USERPROFILE%". Lo myalelo uphinda umendo woluhlu lwangoku lomsebenzisi, olulingana ne-echo_home kwiinkqubo ze-Unix.
echo %USERPROFILE%
Ukucacisa iKhowudi ye-Echo_HOME
Ukuqala ngokuqonda 'i-echo,' yinyani, umyalelo womyalelo kwi-Windows (cmd) osetyenziswa ikakhulu ukubonisa umbhalo okanye umyalezo kwisikrini. Ngaphaya koko, 'USERPROFILE' yimeko-bume eguquguqukayo kwi-Windows egcina umendo woluhlu lweprofayile yomsebenzisi wangoku.
Ngaphakathi kwekhowudi, isimboli yepesenti (%) isongelwe USERPROFILE kukucacisa ukuba kukutshintsha kwemeko-bume. Ngokusebenzisa lo myalelo ungasentla kwiWindows cmd, iya kubonisa indlela kulawulo lwakho lwangoku lomsebenzisi.
Ukuqonda iWindows CMD kunye neJava scriptings
IWindows cmd yitoliki yomgca womyalelo ongagqibekanga wenkqubo yokusebenza yeWindows. Inokwenza iifayile zebhetshi okanye izikripthi, kunye nemisebenzi ezenzekelayo ebalulekileyo kwimimandla yophuhliso. Sisixhobo esinamandla abaphuhlisi abasisebenzisayo ukuqalisa izikripthi okanye iinkqubo kunye nemiba yokusombulula ingxaki kwi-Windows.
Kwelinye icala, iJava lulwimi lwenkqubo olujolise kwinto esetyenziswa ngokubanzi ekudaleni usetyenziso oluntsonkothileyo. Ngelixa ingasetyenziswanga ngokudibeneyo ne-cmd yokubhala ngenxa yeeparadigms zeprogram ezahlukeneyo, ulwazi lwayo luluncedo kwaye lunokunceda kakhulu ekuqondeni ukuba iinkqubo zisebenza njani kwinqanaba elisezantsi.
Ukuqulunqwa kweNkqubo yeJava kwiWindows CMD
Umyalelo 'javac' usetyenziselwa ukuqokelela iinkqubo zeJava, ngelixa 'java' isetyenziselwa ukuziphumeza. Ukwenza ezi ntshukumo, ikhithi yophuhliso lweJava (i-JDK) kufuneka ifakwe kunye nezinto eziguquguqukayo zokusingqongileyo. Ngezantsi ngamanyathelo okuqokelela inkqubo yeJava kwi cmd.
- Lawula usebenzisa i-cmd kulawulo apho ifayile yakho ye.java ikhoyo.
- Sebenzisa umyalelo 'wejavac' ukuqokelela inkqubo yakho. Faka endaweni ethi 'MyProgram.java' ngegama lakho lokwenyani lefayile.
javac MyProgram.java
- Ukuba akukho ziphoso kwikhowudi yakho, i-cmd iya kudala ifayile entsha ye-'MyProgram.class' kulawulo olufanayo.
- Emva koko ungasebenzisa umyalelo 'wejava' ukuphumeza inkqubo yakho. Buyisela u-'MyProgram' ngegama leklasi equlethe indlela yakho 'engundoqo'.
java MyProgram
Isiphumo senkqubo yakho yeJava siyakuphinda kwiscreen secmd. Umanyano kunye nokuqonda oku kuqhuba komgca womyalelo kunye nenkqubo yeJava idlala indima ebalulekileyo kuphuhliso lwesoftware kunye nolawulo lwenkqubo.
