以下是必需的程序。
public class Tester { public static int getSecondSmallest(int[] a) { int temp; //对数组排序 for (int i = 0; i < a.length; i++) { for (int j = i + 1; j < a.length; j++) { if (a[i] > a[j]) { temp = a[i]; a[i] = a[j]; a[j] = temp; } } } //返回第二个最小元素 return a[1]; } public static void main(String args[]) { int a[] = { 11,10,4, 15, 16, 13, 2 }; System.out.println("Second Smallest: " +getSecondSmallest(a)); } }
输出结果
Second Smallest: 4
