Java Program to find Sum of Array

π Introduction
In the world of programming, array manipulation is a common and essential task. One frequent operation is finding the sum of elements in an array.
In this tutorial, we will explore a simple yet effective javaprogram that calculates the sum of elements in an array.
π Example
Let's dive into the java code that accomplishes this task.
public class SumOfArray {
// Function to find the sum of array elements
static int findSumOfArray(int[] arr) {
int sum = 0;
for (int value: arr) {
sum += value;
}
return sum;
}
// Driver program
public static void main(String[] args) {
// Replace these values with your array elements
int[] array = {1, 2, 3, 4, 5};
// Call the function to find the sum
int sum = findSumOfArray(array);
// Print the result
System.out.println("Sum of the array elements: " + sum);
}
}
π» Testing the Program
To test the program with different array elements, simply replace the values in the array initialization.
Sum of the array elements: 15
Compile and run the program to see the sum of the array elements.
π§ How the Program Works
- The program defines a class SumOfArray containing a static method findSumOfArray that takes an array as input and returns the sum of its elements.
- Inside the method, it iterates through the array using an enhanced for loop and accumulates the sum.
- The main method initializes an array with sample values.
- It then calls the findSumOfArray method and prints the result.
π§ Understanding the Concept of Sum of Array
Before diving into the code, it's essential to understand the concept of finding the sum of array elements. The sum of an array is obtained by adding up all the elements it contains.
For example, in the array {1, 2, 3, 4, 5}, the sum is 1 + 2 + 3 + 4 + 5 = 15.
π’ Optimizing the Program
While the provided program is straightforward, you can explore optimizations such as handling large arrays, incorporating error checking, or parallelizing the sum calculation for improved performance.
Feel free to incorporate and modify this code as needed for your specific use case. Happy coding!
