public class ArrayAverage { public static void main(String[] args) { int[] arr = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; // 给定的一维数组 // 求平均值 int sum = 0;for (int i = 0; i < arr.length; i++) { sum += arr[i];} double avg = (double) sum /...
下面的代码示例展示了一个简单的 Java 工具类,用于计算给定数组的平均值。 publicclassAverageUtils{publicstaticdoublecalculateAverage(int[]nums){if(nums==null||nums.length==0){thrownewIllegalArgumentException("Input array should not be empty");}intsum=0;for(intnum:nums){sum+=num;}return(double)su...
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...
每个Thread 中都具备一个 ThreadLocalMap ,而 ThreadLocalMap 可以存储以ThreadLocal 为 key,Object对象为 value 的键值对。 ThreadLocalMap(ThreadLocal<?> firstKey, Object firstValue) {} 比如我们在同一个线程中声明了两个 ThreadLocal 对象的话,会使用 Thread 内部都是使用仅有那个ThreadLocalMap 存放数据的,...
int[] array = {1, 2, 3, 4, 5}; int sum = 0; for (int num : array) { sum += num; } double average = (double) sum / array.length; 复制代码 使用Stream API:Java 8引入的Stream API提供了一种便捷的方式来对集合进行操作,可以使用stream()方法将集合转换为流,然后使用mapToInt()方法...
Double average = ids.stream().collect(Collectors.averagingInt(value -> value)); System.out.println("平均值:" + average); // 数据统计信息 IntSummaryStatistics summary = ids.stream().collect(Collectors.summarizingInt(value -> value)); System.out.println("数据统计信息: " + summary); ...
