Finding The Difference Between The Sum Of Even And Odd Elements In An ArrayList
Introduction
This guide will take you through a step-by-step process to find the difference between the sum of even and odd elements in an ArrayList with a comprehensive Java program.
As you have now understood the concept, first try to solve the problem by yourself before you look into the below solution.
Step-by-Step Solution
Step 1: Import Necessary Packages
Step 2: Create and Populate the ArrayList
Step 3: Calculate the Sums
Create variables to store Even Elements sum and Odd Elements Sum
If the element is even add it to Even sum and if it is odd, add it to Odd sum
Step 4: Calculate the Difference
Step 5: Display the Result
The Complete Code
Combining all the steps, the complete Java program is as follows:
Explanation
The ArrayList class is imported.
An ArrayList named numbers is created and populated with integers.
Two variables, sumEven and sumOdd, are used to calculate the sums of even and odd elements.
A loop is used to iterate through each element in the ArrayList and update the sums accordingly.
The difference between the sums is calculated.
The result, including the sums of even and odd elements and the difference, is displayed to the console.
