Question

JAVA语言编程:有一个一维数组,内放10个学生成绩,编程求出平均分,最高分和最低分

Answer 1

//定义你的数组arrays;
arrays = sort(arrays);
Double min = arrays[0];//最低分;
Double max = arrays[9];//最高分;
Double pingjun = 0.0;
for(int i=0;i<arrays.length;i++){
pingjun = arrays[i]/10 +pingjun;
}
pingjun是你要的平均值

Answer 2

double sum=0,max=0,min=999;

for(int i=0;i<arr.length;i++)
{
if(arr[i]>max) max=arr[i];
if(arr[i]<min) min=arr[i];
sum+=arr[i];

}
System.out.println("avg:"+(sum/arr.length));
System.out.println("max:"+max);
System.out.println("min:"+min);

Answer 3

for一下就好了
