Mencipta GUI Catur Ayunan Yang Teguh dan Boleh Resizable
Swing, perpustakaan Java untuk mencipta antara muka pengguna grafik (GUI), menawarkan rangka kerja yang berkuasa untuk membina aplikasi yang mantap dan boleh disesuaikan. Dalam artikel ini, kami akan menumpukan pada mencipta GUI Catur berasaskan Swing yang boleh diubah saiz, memenuhi keperluan berikut:
