数组最大值、最小值、元素和、平均值

public class A3 {
    public static void main(String[] args) {
        //数组最大值、最小值、元素和、平均值
        //定义数组
        int[] a = {1,3,5,-2,4,6};

        int max = a[0];//认为数组第一个元素就是最大值
        int min = a[0];
        int pj = 0;
        int sum = 0;
        for (int i =0;i<a.length;i++){
            if (a[i]>max){
                max = a[i];
            }
            if (a[i]<min){
                min = a[i];
            }
            sum += a[i];
        }
        pj = sum / a.length;
        System.out.println("最大值为:"+max);
        System.out.println("最小值为:"+min);
        System.out.println("平均值为:"+pj);
        System.out.println("总和为:"+sum);
