Unity Engine is a popular game development engine that allows developers to create games for a variety of platforms, including PC, mobile, and consoles. In order to develop games using Unity Engine, you'll need to set up several tools, including the Java Development Kit (JDK), Android Software Development Kit (SDK), Android Native Development Kit (NDK), and Gradle. In this article, we'll walk you through the steps to download and set up these tools for Unity Engine development.

Step 1: Download and Install JDK

The Java Development Kit (JDK) is required for Unity Engine development on Windows and Mac. Here's how to download and install JDK:
