找不出问题在哪里，方法名一直报错！

Question

public class YY {

 private int f(){

int[] s={18,23,21,19,25,29,17}; 

   int max=0;

    for(int i=0;i<s.length;i++){

    if(max<s[i])

    max=s[i];

    return max;

    }

   

    

   

    }

 public static void main(String[] args){

YY pp=new YY();

 

pp.f();

System.out.println("最大年龄为："+pp.f());

 }

 }

Answer 1

private int f()；这个方法缺少返回值，将return max;挪出来放到for循环后边；如下：private int f() { int[] s = { 18, 23, 21, 19, 25, 29, 17 }; int max = 0; for (int i = 0; i < s.length; i++) { if (max < s[i]) max = s[i]; } return max; }
