Another method to concatenate two arrays in Java is arraycopy() method. This method takes the values of arrays and merges them into one. The below example shows how this can be done for integer arrays. Example Codes: import java.util.Arrays; public class SimpleTesting { public static void ...
In this short article, you will learn about different ways to concatenate two arrays into one in Java. Using A Loop The simplest way to concatenate two arrays in Java is by using the for loop: int[] arr1 = {1, 2, 3, 4}; int[] arr2 = {5, 6, 7, 8}; // create a new ...
To concatenate two arrays and extract unique values, the easiest way is to use thenumpy.union1d()method, it performs the union operation on one-dimensional arrays, and returns the unique, sorted array of values that are in either of the two input arrays. Let us understand with the help of...
