使用BubbleSort方法求平均值

你只需要编辑一下。只需在程序中添加一个变量平均值,如果需要整数平均值,则添加int variable,如果需要精确结果,则添加float(如下代码所示)。将所有元素求和为变量和(整数元素),然后将其除以元素总数(基础数学!!!)。就这样,打印出来,你就完成了。

您的程序应该如下所示:

public static void main(String[] args) {
int num, i, j, sum=0;
float avg=0;
double temp;
@SuppressWarnings("resource")
Scanner input = new Scanner(System.in);

System.out.println("Enter the amount of Numbers you want to sort:");
num = input.nextInt();

double array[] = new double[num];

System.out.println("Enter " + num + " Number: ");

for (i = 0; i < num; i++)
    array[i] = input.nextDouble();

for (i = 0; i < (num - 1); i++) {
    for (j = 0; j < num - i - 1; j++) {
        if (array[j] > array[j + 1]) {
            temp = array[j];
            array[j] = array[j + 1];
            array[j + 1] = temp;
        }
    }
}

System.out.println("Sorted list:");

for (i = 0; i < num; i++)
    System.out.println(array[i]);

for (i = 0; i < num; i++)
 sum = sum+array[i];
avg=sum/num;
System.out.println("Average : "+avg);
 }
}

 int avg = 0;   
 for (i = 0; i < num; i++) {
     avg = avg + array[i];
 }
 avg = avg / array.length();
