為什么這樣不對(duì)呢
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(jì)算成績(jī)總分，并返回總分
?public static int sum() {
????? sum =? score1+score2;
????? return sum;
?}
?public static void main(String[] args) {
???????
??????? // 調(diào)用靜態(tài)方法sum并接收返回值
??int allScore = HelloWorld.sum()
???????
??System.out.println("總分：" + allScore);
?}
}

都是細(xì)節(jié)問題呀，sum = ?score1+score2;這句前面加個(gè)int。
int allScore = HelloWorld.sum()這句后面加個(gè)分號(hào)

sum = ?score1+score2;這句前面加個(gè)int。int?sum = ?score1+score2;
int allScore = HelloWorld.sum()這句后面加個(gè)分號(hào)。int allScore = HelloWorld.sum();
問題不大，需要細(xì)心。

靜態(tài)方法sum里的局部變量sum你沒有申明吧，前面加個(gè)int
