package com.myfirst;
import java.util.Arrays;
public class Helloworld {
public static void main(String[] args){
Helloworld yu=new Helloworld();
yu.num(98,52,81,79);
}
public int num(int []scores){
Arrays.sort(scores);
System.out.println(Arrays.toString(scores));
int a=0;
for(int i=0;i<scores.length;i++){
a++;
}
System.out.println("成绩的个数为:"+a);
return a;
}
}
为什么对yu.num(98,52,81,79);中的num报错呢?找不到这个方法。。。
The method num(int[]) in the type Helloworld is not applicable for the arguments (int, int, int, int)
