為什么不對(duì)？
public class HelloWorld {
???
??? // 定義靜態(tài)變量score1
??? static int score1 = 86;
??? // 定義靜態(tài)變量score2
?????????? 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 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 =sum();
???????
??System.out.println("總分：" + allScore);
?}
}

int score2 = 92;前面缺個(gè)static，
int allScore =sum();應(yīng)該是int allScore =HelloWorld.sum();,你這是將sum()直接作為一個(gè)變量賦給allScore了

定義靜態(tài)變量score2? ?前面忘了加static? int xx 是常量
