Program For Finding Second Largest Element Of Array Codebaji To find second largest element, first find the largest element. to find largest element, first declare a smallest element. max = integer.min value. compare each element with this. if element larger than this is found, update max value. continue this process until maximum element found. now for finding second largest, again repeat the same. Find second largest element in an array.
Program For Finding Second Largest Element Of Array Codebaji Bubble sort works on simple concept of shifting the biggest element at the end in every pass it does (in case of increasing order). since you need the first and second largest element in an array, 2 passes of bubble sort will do the trick. the last element will be the largest and the second last element will be second largest. We can find the second largest number in an array in java by sorting the array and returning the 2nd largest number. let's see the full example to find the second largest number in java array. public class secondlargestinarrayexample {. public static int getsecondlargest (int[] a, int total) {. int temp;. Now, the size of the array returned by findlargest () is log2(n) 2, out of which log2(n) elements are the ones with which the largest element is compared. hence, to find the second largest element, the largest among these log2(n) elements is calculated using log2(n) – 1 comparisons. therefore, the total number of comparisons = n – 1 log. The user is asked to enter the elements of array. the program then finds the second largest element of the array using for loop. to understand this program, you should have the basic knowledge of c loops, if else statement and c arrays. example: program to find the second largest element in an array of n elements.

Step by step working of the above program code: let us assume that a user enters the number of elements as 5. and the user enters the elements as {6 3 7 9 5}. so it stores the elements in the array a []= {6,3,7,9,5}. now it assigns the value of a [0] to large and s large (i.e. large=s large=6). then it assigns the value of i=1 and the loop. Public static void swapmaxminelement(int arr[], int maxelementpos, int minelementpos) {. *to swap max and min numbers, take a temporary variable, and follow the below step, 1) assign maximum number to temporary vaiable. 2) assign minimum number to maximum number. 3) asign temporary vaiable to minimum number* . int temp; temp = arr[maxelementpos];.
