Java interview Program to find second smallest number in an integer array without sorting the elements.

1. package com.instanceofjava;
2. class SecondSmallestNumber{
3.  
4. int[] x ={10,11,12,13,14,6,3,-1};
5.  
6.         int small=x[0];
7.  
8.  for(int i=0;i<x.length;i++)
9.  {
10.         if(x[i]<small)
11.         {
12.         small=x[i];
13.         }
14.  }
15.  
16.    int sec_Small=x[0];
17.  
18. for(int i=0;i<x.length;i++)
19.  {
20.         if(x[i]<sec_Small && x[i]!=small)
21.         {
22.         sec_Small=x[i];
23.         }
24.   }
25.  
26.         System.out.println("Second Smallest Number: "sec_Small);
27.         }
28. }

Output:
 

1. Second Smallest Number:3
