Bagaimana untuk menulis permainan kapal selam menggunakan Java?

Yang pertama ialah tetingkap yang ditakrifkan dalam kaedah utama (ini adalah format tetap, tidak mengapa jika anda tidak tahu bagaimana untuk melakukannya, hanya Ctrl+c+v, anda pada dasarnya boleh memahaminya hanya dengan melihat data )

Tulis kelas super Kelas super perlu mempunyai lebar dan ketinggian kapal selam, caj kedalaman, lombong dan kapal perang, serta koordinat x dan y apabila ia muncul, serta kelajuan pergerakannya. Gambar semua objek, kaedah pergerakan semua objek, dan perlanggaran

dan kemudian tulis kelas terbitan Menurut mengalahkan kapal selam lombong, kapal perang akan mendapat satu nyawa, dan mengalahkan kapal selam lain akan mendapat mata perlu ditakrifkan Dua antara muka, satu digunakan untuk menambah nyawa, satu lagi digunakan untuk menambah mata

Kod lengkap adalah seperti berikut (anda boleh mencari gambar sendiri, cuma tukar kelas Imej dan lebar dan ketinggian setiap objek)
