Create a program that calculates the average of different ages:ExampleGet your own Java Server // An array storing different ages int ages[] = {20, 22, 18, 35, 48, 26, 87, 70}; float avg, sum = 0; // Get the length of the array int length = ages.length; // Loop through ...
public class AverageCalculator { public static void main(String[] args) { int[] array = {10, 20, 30, 40, 50}; double sum = 0; for (int num : array) { sum += num; } double average = sum / array.length; System.out.println("Average of the array is: " + average); } } 复...
System.out.printf("Compute the average value of an array of integers except the largest and smallest values: %.2f", x); // Print a new line. System.out.print("\n"); } } Sample Output:Original Array: [5, 7, 2, 4, 9] Compute the average value of an array of integers except ...

int[] array1 = {1,2,3,4,5}; // 定义一 int[] array2 = new int[10]; // 定义二 int[] array3 = new int[]{1,2,3,4,5}; // 定义三 1. 2. 3. 在这三种方式中,Java中定义数组最常用的是方式一。 4. 数组的使用 (1)获取长度 注意事项 使用arr.length 能够获取到数组的长度. ...
程序定义了带可变参数的方法average(),它的功能是返回传递给该方法多个double型数的平均值。该程序调用了average()方法并为其传递三个参数,输出结果为72.0。 在可变参数的方法中还可以有一般的参数,但是可变参数必须是方法的最后一个参数。例如,下面定义的方法也是合法的: 注意:在调用带可变参数的方法时,可变参数是...
