Eli nqaku liza kuthetha malunga nendlela yokuphuma kwi-jshell eyisixhobo se-Java Shell esaziswa ngeJava 9. Kufana ne-REPL esekelwe kumgca womyalelo (Funda-Vavanya-Print Loop) okuvumela ukuba uvavanye ngokukhawuleza ikhowudi yakho ye-Java snippets. Nangona kunjalo, kunokubakho amaxesha apho ufuna ukuphuma kwi-jshell kwaye ubuyele kumyalelo wakho wendlela yokusebenza. Ngaloo nto, siya kuqala ngokubonelela ngesisombululo kulo mba, silandelwe yinkqubo ebanzi yekhowudi. Eli nqaku libandakanya ukuqonda malunga namathala eencwadi anxulumeneyo, imisebenzi, kunye nokunye.
Iphuma kwi-jshell ilula njengokubhala / phuma kwaye ucinezele Ngena. Nangona kunjalo, ukuqonda umxholo osemva kwalo msebenzi ubalulekile kuye wonke umthuthukisi weJava. Iqinisekisa ukusebenzisana okugudileyo kunye ne-jshell kwaye iphucula ukusebenza kwakho konke kwekhowudi.

I-Anatomy yomyalelo / ukuphuma komyalelo
Umyalelo /uphuma ngomnye wemiyalelo emininzi yemeta exhaswa yi jshell. Le meta-imiyalelo iqala ngophawu kwaye ayiyonxalenye yolwimi lweJava. Zisetyenziselwa ukulawula ukuziphatha kweseshoni ye-jshell.
Umyalelo/wokuphuma usetyenziselwa ukuphelisa iseshoni ye-jshell nokubuyisela ulawulo kwindlela yokusebenza. Xa ubhala/uphuma kwaye ucinezele u-Enter, ithumela umyalelo wokuphuma kwi-jshell, othi ke uphelise iseshoni.
Ukuqonda ngokweenkcukacha le meta-miyalelo kunokuphucula kakhulu ukusebenza kwakho ngelixa usebenza ne-Java's REPL.
Ukuqonda eminye iMiyalelo yeMeta
Ukuqonda ezinye iimeta-imiyalelo kwi-Jshell kubaluleke ngokulinganayo. Umzekelo, /help ibonelela ngoluhlu lwayo yonke imeta-imiyalelo. /uluhlu lubonisa zonke iziqwengana ozifakileyo ngexesha leseshoni. /gcina igama lefayile kunokugcina iziqwengana zeseshoni yakho kwifayile. Le miyalelo idlala indima ebalulekileyo ekwenzeni okuninzi kwi jshell.
/help /list /save filename
Kanye njengokuba / ukuphuma kuphelisa iseshoni yakho, le miyalelo ye-meta ikwenza ukwazi ukulawula, ukugcina, kunye nokubuyisela umsebenzi wakho ngokufanelekileyo. Ngokusebenzisa le miyalelo, uya kuba nobuchule ekuhambeni kwi-jshell kwaye ulungelelanise imisebenzi yakho yophuhliso lweJava.
Ukuququmbela, i-jshell sisixhobo esinamandla esivumela abaphuhlisi beJava ukuba bavavanye ngokukhawuleza nangokuchanekileyo iziqwengana zekhowudi. Umyalelo / ukuphuma kunye neminye imiyalelo ye-meta idlala indima ebalulekileyo ekulawuleni ukuziphatha kweJava REPL, ngaloo ndlela iqinisekisa amava ophuhliso lweJava afanelekileyo.
