用jave编写一个程序要求输出一个整数数组中的最大和最小的元素，平均值，所有元素的和

Question

如题所述

Answer 1

下面的程序不处理空数组...

import java.util.Arrays;
public class Test {

public static void main(String[] args) {
int[] array = { 1, 2, 3, 4, 5, };

int[] temp = Arrays.copyOf(array, array.length);
Arrays.sort(temp);

System.out.println("min: " + temp[0]);
System.out.println("max: " + temp[temp.length - 1]);
System.out.println("sum: " + sum(temp));
System.out.println("avg: " + sum(temp) / temp.length);
}

private static int sum(int[] array) {
int sum = 0;
for (int i = 0; i < array.length; ++i)
sum += array[i];
return sum;
}
