An warware: sami girman saka idanu

Java harshe ne mai ƙarfi da ake amfani da shi wajen haɓaka nau'ikan aikace-aikace daban-daban, daga aikace-aikacen hannu zuwa tsarin sikelin kasuwanci. Ɗaya daga cikin ɗawainiya na gama gari don masu haɓakawa shine tantance girman allo na na'ura ko saka idanu inda aikace-aikacen ke aiwatarwa, wanda zai iya rinjayar abubuwa kamar ƙirar UI da UX. Akwai hanyoyi da yawa don cim ma wannan a Java. A cikin wannan bayanin, mun zurfafa cikin hanya mai sauƙi kuma wacce aka fi amfani da ita.

Bayan duban bayanin bayanin, zamu tattauna zurfinsa, bayanin mataki-mataki na lambar. Za a kuma ba da haske kan muhimman ayyuka da ɗakunan karatu da ke cikin wannan matsala. Manufar ita ce a ba ku kyakkyawar fahimtar yadda Java ke hulɗa da tsarin ku don samo cikakkun bayanai.

Wannan ita ce maganin matsalarmu:

import java.awt.*;

public class Main {

    public static void main(String[] args) {
        Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
        double width = screenSize.getWidth();
        double height = screenSize.getHeight();
        System.out.println("Screen Width: "+ width);
        System.out.println("Screen Height: "+ height);
    }
}

Lambar mu tana farawa ta hanyar shigo da kunshin java.awt.*, babban ɗakin karatu wanda ke samar da mahimman APIs don ƙirƙirar mu'amalar mai amfani da hoto.

Toolkit.getDefaultToolkit().getScreenSize()

Toolkit babban aji ne hade a cikin kunshin java.awt. Wannan ajin yana da hanyar mai suna getDefaultToolkit(). Kamar yadda sunan ke nunawa, yana ɗauko tsoffin kayan aikin kayan aiki. Tare da kowane Toolkit, za mu iya kiran hanyar getScreenSize(). Yana dawo da wani abu Dimension mai riƙe da faɗin allo da tsayinsa. A fasaha, yana ɗaukar girman girman abin dubawa na farko, wanda yawanci ya isa idan kuna aiki tare da tsarin kulawa guda ɗaya.

Za mu iya cire nisa da tsayin allon ta hanyar kiran hanyoyin getWidth () da kuma getHeight() na abin Dimension. Ƙimar da aka samu suna cikin pixels kuma suna wakiltar girman allo. Wannan bayanin yana da amfani don saita girman ɓangaren ɓangaren UI mai ƙarfi ko kuma idan abubuwan haɗin gwiwa sun daidaita bisa waɗannan ƙimar.

System.out.println ("Nisa allo:"+ nisa);

Bayan samun faɗi da tsayi, lokaci yayi da za a buga waɗannan ƙimar. Ana amfani da aikin na gargajiya System.out.println() anan. Muna buga faɗin allo ta amfani da haɗar kirtani don haɗa ainihin "Nisa allo:" tare da ƙimar faɗin.

Hakazalika, muna buga tsayi a cikin layi na gaba. Na'ura wasan bidiyo zai ɗauki waɗannan sakamakon, yana nuna girman allon PC ɗin ku lokacin da kuke gudanar da wannan shirin.

Tare da ilimin da aka samu a nan, ya kamata ku iya yin amfani da ikon Java don yin hulɗa tare da saitunan tsarin - ba kawai girman mai saka idanu ba. Lallai, daular Java tana da ma'ana da ban sha'awa, tana cike da ɗimbin fasali da ayyuka cikakke don tunkarar ɗawainiya da yawa. Daga ƙirar UI zuwa samun takamaiman bayanan tsarin, Java yana da abubuwa da yawa don bayarwa. Happy codeing!
