public?class?HelloWorld?{????????//?定義靜態變量score1????static?int?score1?=?86;????//?定義靜態變量score2 static???int?score2?=?92;?????//?定義靜態方法sum，計算成績總分，并返回總分 public?static?int?sum()?{???????return?score1+score2;???????????? } public?static?void?main(String[]?args)?{????????????????//?調用靜態方法sum并接收返回值 int?allScore?=?HelloWord.sum();???????? System.out.println("總分："?+?allScore); }}
