Java, being a versatile and widely used programming language, offers multiple ways to perform array addition. In this guide, we will explore different methods and approaches to add two arrays in Java.

Method 1: Using a Loop

One of the most straightforward methods to add two arrays in Java is by using a loop. You can iterate through the arrays and add corresponding elements. Here's an example:

In this example, array1 and array2 are added element-wise, and the result is stored in the result array. Adjust the size of the result array based on your requirements.

Method 2: Using Apache Commons Lang Library

Apache Commons Lang library provides a convenient method for adding arrays without writing custom loops. First, you need to import the library into your project. Then, you can use the ArrayUtils class to add arrays:

In this method, the ArrayUtils.addAll() function concatenates the two arrays, providing a simple and efficient way to add arrays.

Method 3: Using Java Streams

With Java 8 and later versions, you can use streams to add arrays in a concise and readable way:

In this example, Arrays.stream() is used to convert the arrays into streams. The zipWith() function combines the corresponding elements, and toArray() converts the result back into an array.

These methods provide different approaches to add two arrays in Java. Choose the one that best fits your requirements and coding style.

Happy Coding!
