Question

用JAVA编写一程序,求数组中的最大数、最小数和平均值

Answer 1

public class Test
{
public static void main(String[] args)
{
double[] array = {10.2, 33.5, 2.85, 11.4, 4.6, 5,55};
int arrayLen = array.length;
double maxValue = array[0];
double minValue = array[0];
double sum = 0;

for (int i=0; i<arrayLen; i++)
{
sum += array[i];
if (maxValue < array[i])
{
maxValue = array[i];
}
if (minValue > array[i])
{
minValue = array[i];
}
}

System.out.println("最小数" + minValue);
System.out.println("最大数" + maxValue);
System.out.println("平均数" + sum/arrayLen);
}
}
