Java数组的最大值和最小值

public static void main(String args[]){
    int a[] = {1,3,5,-2,4,6};
    int count =0;
    double avg = 0;

    int max = a[0];
    int small = a[0];

    for (int i = 0;i a[i]){
            small = a[i];
        }

    }

    avg = (double)count / a.length;

    System.out.println("数组的长度为:"+a.length);

    System.out.println("最大值为:"+max);
    System.out.println("最小值为"+small);
    System.out.println("数组的和为："+ count);
    System.out.println("数组的平均值为:"+avg);
