Corak Bintang di Jawa

Dalam dokumen ini, pertama sekali, kita akan melihat cara menggunakan pengaturcaraan Java untuk berfungsi dengan program corak Bintang. Corak bintang ialah program corak Java biasa yang digunakan secara meluas untuk meningkatkan pemikiran logik dan pengetahuan kawalan aliran. Anda perlu menggunakan dua gelung atau tiga gelung (bergantung pada program) untuk menunjukkan corak Bintang dalam Pengaturcaraan Java. Gelung pertama ialah gelung luar dan gelung kedua ialah gelung dalam yang masing-masing menunjukkan baris dan lajur.

Dokumen ini berguna untuk pengaturcara Java yang ingin mengetahui tentang corak reka bentuk untuk meningkatkan keupayaan reka bentuk dan pembangunan berorientasikan objek mereka.

Contoh Corak Bintang

Mari kita bincangkan beberapa contoh untuk memahami konsep corak dalam Jawa dengan mudah.

Contoh #1

Kod:

import java.util.Scanner;
public class FirstPattern
{
public static void main(String[] args)
{
Scanner scanner = new Scanner(System.in);
System.out.println("Please provide number of rows to print... ");
int myrows = scanner.nextInt();
System.out.println("\nThe star pattern is... ");
for (int m = 1; m <= myrows; m++)
{
for (int n = 1; n <= m; n++)
{
System.out.print("*");
}
System.out.println();
}
}
}

Kesimpulan

Setakat ini, kami telah membincangkan pelbagai jenis corak dalam bahasa pengaturcaraan Java. Corak ini adalah amalan terbaik yang digunakan oleh pereka perisian berorientasikan objek berpengalaman. Pengguna boleh menggunakan corak reka bentuk ini untuk perbincangan reka bentuk perisian berorientasikan objek. Dengan bantuan corak ini, pembangun yang tidak berpengalaman boleh mempelajari reka bentuk perisian dengan cepat dan lebih pantas.
