An warware: sami millise seconds na yanzu

Tabbas, zan rubuta cikakken labarin game da samun milliseconds na yanzu a Java.

Fahimtar Lokaci da ma'aunin sa yana da mahimmanci, musamman a duniyar fasaha inda daidaito ke da mahimmanci. A cikin Java, ana iya auna lokaci ta hanyoyi da yawa. Amma, ษ—ayan mafi daidaitattun hanyoyin shine ta amfani da millise seconds. Milliseconds suna da amfani musamman ga ayyuka kamar masu ฦ™ididdige ฦ™ididdigewa, rajistan ayyukan, duba latency da ฦ™ari. Milliseconds suna samar da ingantacciyar hanyar daidaita lokacin, wanda zai iya zama mai mahimmanci a yawancin aiwatar da fasaha.

Java yana ba mu damar debo lokacin yanzu a cikin millise seconds ta hanyar ajin tsarin. Ajin Tsarin ya ฦ™unshi filayen aji da yawa masu amfani da hanyoyin da ba za a iya nan take ba don haka galibi ana amfani da shi don samun bayanai da albarkatu masu alaฦ™a da tsarin.

Nemo Lokacin Yanzu a cikin Milliseconds

A cikin Java, ana iya samun lokacin da ake yanzu a cikin millise seconds ta amfani da hanyar `System.currentTimeMillis()` wacce ta kasance ajin 'System'. Yana dawo da lokacin na yanzu a cikin milli seconds daga lokacin Epoch (1970-01-01 00:00:00.000 GMT).

long currentTimeInMilliseconds = System.currentTimeMillis();
System.out.println("Current time in milliseconds: " + currentTimeInMilliseconds);

Anan, muna amfani da hanyar `System.currentTimeMillis()' wanda ke ba da lokacin da ake yanzu cikin miliyon daฦ™iฦ™ai tun tsakiyar dare, Janairu 1, 1970 UTC.

Bayanin mataki-mataki

Bari mu rushe lambar Java da aka ambata a baya:

1. `long currentTimeInMilliseconds = System.currentTimeMillis();` โ€“ Wannan layin code yana kiran hanyar `currentTimeMillis()` akan ajin `System`. ฦ˜imar dawowa ta nau'in 'dogon' ce wacce ke da ikon riฦ™e manyan lambobi yayin da lokaci a cikin ms ya ketare iyakoki cikin sauฦ™i.

2. `System.out.println ("Lokaci na yanzu a cikin millise seconds:" + currentTimeInMilliseconds);` - Wannan umarni ne mai sauฦ™i don buga lokacin da aka samu a cikin milliseconds zuwa na'ura wasan bidiyo.

Class Class a cikin Java

Ajin 'System' ษ—aya ne daga cikin azuzuwan da aka gina a cikin Java, wanda ke zaune a cikin kunshin java.lang. Wannan ajin yana ba da hanyoyi da fagage da yawa masu alaฦ™a da tsari ko muhallin da na'urar Virtual na Java ke aiki. ฦŠayan irin wannan hanyar ita ce hanyar 'currentTimeMillis()'.

Fahimtar halin yanzuTimeMillis()

Hanyar ''currentTimeMillis()' ginannen hanya ce a cikin Java wacce ke dawo da lokacin da ake ciki a cikin millise seconds. Ana wakilta lokacin azaman adadin millise seconds tun daga Janairu 1, 1970, 00:00:00 GMT (zamanin), wanda shine daidaitaccen hanyar wakiltar lokaci a yawancin tsarin. Wannan hanyar ba ta da lafiya kuma za a iya amfani da ita don auna lokacin da ya wuce, wanda ke da amfani azaman kayan aiki mai sauฦ™i.

Wannan jagorar asali ce kawai don fahimtar yadda ake samun milliseconds na yanzu a Java. ฦ˜arin bincike a cikin 'System' ajin zai taimaka muku gano ฦ™arin aikace-aikace masu ban sha'awa.
