Max1 = max2 = int_min. Sort the array using arrays.sort (). We can find the second smallest number in an array in java by sorting the array and returning the 2nd element.

If Current Element Is Greater Than Highest Assign Secondhighest = Highest;

But before moving forward, if you are not familiar with the concepts of the array, then do check the article arrays in java. You can sort the array and then return second last element in the array but it will be done in o (nlogn) time, algorithm: In this example, we have given an unsorted array of integers.

Use A Separate Variable For That And Increment When You Add A New Value.

With each pass, we find the next smallest element and place it next. Simple approch you can use in this case is to sort the array first using sorting algorithm and then print the last second element. Then, compare 2nd and 3rd elements if the second element is greater than the 3rd swap them.

Arraylist Arraylist = New Arraylist ();

Logic to find second largest element. By searching maximum and second maximum element in single scan : Enter length of the array:
