求和居然报错?
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;
int avg=avg(sum);
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);
}
}
报错:请检查输出是否匹配:年龄综合:105,再试试!
