有一个int数组{1,3,5,-2,4,6}，要求获取：最大值、最小值、元素和、平均值

public class zy { public static void main(String[] args) { int a[] = {1, 3, 5, -2, 4, 6}; int max, min, sum, avg; sum = addSum(a); max = maxVlaue(a); min = minVlaue(a); avg = avgg(a); System.out.println("数组和为 "+sum); System.out.println("数组最大值为 "+max); System.out.println("数组最小值为 "+min); System.out.println("数组平均数为"+avg); } private static int avgg(int[] a) { int avg=0; int sum=0; for (int i = 0; i < a.length; i++) { if (sum<a[i]){ sum=sum+a[i]; } avg=sum/a.length; } return avg; } private static int minVlaue(int[] a) { int min=0; for (int i=0;i<a.length;i++){ if (min > a[i]) { min=a[i]; } } return min; } private static int maxVlaue(int[] a) { int max = 0; for (int i = 0; i < a.length; i++) { if (max<a[i]){ max=a[i]; } } return max; } private static int addSum(int[] a) { int sum=0; for (int i=0;i<a.length;i++){ sum=sum+a[i]; } return sum; } }
