是可以直接調(diào)用啊，因為sum方法有返回值，所以定義了一個變量去接收返回值啊

可以直接調(diào)用System.out.println(sum());

可以直接調(diào)用啊

public?class?HelloWorld?{
????
????//?定義靜態(tài)變量score1
????static?int?score1?=?86;
????//?定義靜態(tài)變量score2
????static?int?score2?=?92;?

????//?定義靜態(tài)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(diào)用靜態(tài)方法sum并接收返回值
????????int?allScore?=?sum();????????
????????System.out.println("總分："?+?allScore);
????}
}
