因为你--age1了
public class HelloWorld{
public static void main(String[] args) {
int age1=24;
int age2=18;
int age3=36;
int age4=27;
int sum = age1+age2+age3+age4;
double avg = sum/4;
int minus = age1-age2;
int newAge = --age1;
System.out.println("年龄总和："+sum);
System.out.println("平均年龄："+avg);
System.out.println("年龄差值："+minus);
System.out.println("自减后的年龄："+newAge);
}
}
