請(qǐng)問(wèn)我這是哪錯(cuò)了
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() {
???? int kxf = 0;
???? kxf = score1 + score2;
???? return kxf;
?}
?public static void main(String[] args) {
???????
??????? // 調(diào)用靜態(tài)方法sum并接收返回值
??int allScore = HelloWorld.kxf();
???????
??System.out.println("總分：" + allScore);
?}
}

你調(diào)用的是靜態(tài)方法的返回值，應(yīng)該這樣：
public static void main(String[] args) {
int allScore = Dem03.sum();
? System.out.println("總分：" + allScore);
}
或者直接調(diào)用靜態(tài)方法：
public static void main(String[] args) {
? System.out.println("總分：" + sum());
}

方法名錯(cuò)誤
