The configuration of Java environment variables is very important for developers and system administrators. It can help us run Java programs correctly in Windows systems. The following are specific steps and code examples on how to configure Java environment variables in Windows systems.
First, you need to download the Java Development Kit (JDK) for Windows systems from the official Oracle website. After the download is complete, follow the instructions of the installation wizard to install. After the installation is complete, remember the installation path because we will need it next.
