Date: 2024-07-18

This Java Code Geeks article details three methods for finding the second smallest number in a Java array. The first sorts the array and selects the second element. The second iterates through the array, tracking the smallest and second smallest values. The third utilizes a Min Heap (PriorityQueue) to efficiently extract the second smallest element. Each method's efficiency varies depending on the application's needs. Read more about these approaches and their comparative advantages here.
