Java程序在数组中查找最大,最小,第二大,第二小
要查找数组中最大,最小,第二大,第二小的代码,代码如下-
示例
import java.util.*; public class Demo { public static void main(String []args){ int arr[] = {55, 10, 8, 90, 43, 87, 95, 25, 50, 12}; System.out.println("Array = "+Arrays.toString(arr)); Arrays.sort(arr); System.out.println("Sorted Array = "+Arrays.toString(arr)); System.out.println("Smallest element = "+arr[0]); System.out.println("2nd Smallest element = "+arr[0]); System.out.println("Largest element = "+arr[9]); System.out.println("2nd Largest element = "+arr[8]); } }
输出结果
Array = [55, 10, 8, 90, 43, 87, 95, 25, 50, 12] Sorted Array = [8, 10, 12, 25, 43, 50, 55, 87, 90, 95] Smallest element = 8 2nd Smallest element = 8 Largest element = 95 2nd Largest element = 90
示例
现在让我们来看另一个示例:
import java.util.*; public class Demo { public static void main(String []args){ int a; int arr[] = {55, 10, 8, 90, 43, 87, 95, 25, 50, 12}; System.out.println("Array = "+Arrays.toString(arr)); int count = arr.length; for (int i = 0; i < count; i++) { for (int j = i + 1; j < count; j++) { if (arr[i] > arr[j]) { a = arr[i]; arr[i] = arr[j]; arr[j] = a; } } } System.out.println("Smallest: "+arr[0]); System.out.println("Largest: "+arr[count-1]); System.out.println("Second Smallest: "+arr[1]); System.out.println("Second Largest: "+arr[count-2]); } }
输出结果
Array = [55, 10, 8, 90, 43, 87, 95, 25, 50, 12] Smallest: 8 Largest: 95 Second Smallest: 10 Second Largest: 90
