2、子類，該程序用于畫界面，所有的圖形全都畫在View類的對象中。l Aircraft類：該類是飛行器的抽象父類，提供飛行器的一些共有屬性，抽象方法等，繼承了線程類Thread。l ShenEight類：該類是Aircraft的子類，神州八號類，可以繞地球飛行，并且可以與指定的TianGong類對象完成對接任務(wù)。l TianGong類：該類是Aircraft的子類，天宮類，可以實(shí)現(xiàn)繞地球飛行，并且可以在與指定的ShenEight對象對接后控制ShenEight對象一起運(yùn)動。l ParentBarbette類：該類是大炮的抽象父類,提供大炮的一半屬性，以及抽象方法。l ComBarbette類：該類

3、是ParentBarbette類的子類，并且實(shí)現(xiàn)了Rounnable接口，該類對象由線程控制，控制大炮發(fā)炮的速度等，攻擊圍繞地球運(yùn)動的飛行器。l PlayerBarbette類：該類是ParentBarbette類的子類，用于攔截?cái)橙说呐趶?。?shí)現(xiàn)了KeyListener接口，可以響應(yīng)鍵盤的空格以及上下左右方向鍵。按下空格鍵，玩家炮發(fā)出炮彈，方向鍵可以移動炮口，使其瞄準(zhǔn)目標(biāo)。l CountScore類： 該類是記分類，在游戲中，該類可以通過攔截是否成功或者是敵方炮彈是否攻擊到飛行器來進(jìn)行加減分，從而判斷是否過關(guān)等等。三：程序主要類的實(shí)現(xiàn)：（1）Continent類：public class Co
