## Program Description

Write a java program to find second largest number in array.There are multiple ways to achieve this. We can sort any given array in a descending order and pick the second index element.The main concept here is to sort the given array.This can be achieved via `Arrays.sort()`

or `Collection.sort()`

and once the given array is sorted the second largest number can be easily found.

package com.devglan.set2; public class SecondLargestInArray { public int findSecondLargestNumberInArray(int[] a){ int temp; 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; } } } return a[a.length - 2]; } public static void main(String[] args){ SecondLargestInArray array = new SecondLargestInArray(); int a[]={4,7,55,16,33,27}; System.out.println("Second largest number in given array is " + array.findSecondLargestNumberInArray(a)); } }
