public class HelloWorld {
static int score1 = 86;
static int score2 = 92;
public static int sum() {
int sum0=score1+score2;
return sum0;
}
public static void main(String[] args) {
// 调用静态方法sum并接收返回值
int allScore=sum()；
System.out.println("总分：" + allScore);
}
}
static int score1 = 86;
int score2 = 92;
public static int sum() {
Demo dd= new Demo();
return score1+dd.score2;
}
public static void main(String[] args) {
Demo dd= new Demo();
System.out.println("总分：" + dd.sum());}不明白答案的思路
