Installation steps on common platforms: 1. Install the Java virtual machine on Windows: download JDK, run the installer, configure environment variables, and verify the installation; 2. Install the Java virtual machine on macOS: use Homebrew to install JDK, manually download JDK, run the installer, and verify the installation; 3. Install the Java virtual machine on Linux: Use the package manager to install OpenJDK, manually download the JDK, run the installer or unzip the file, and verify the installation.

2. Run the installation program:
Double-click the downloaded installation program.
Follow the installation program prompts to install. You may need to select options such as the installation directory.
3. Configure environment variables (optional):
After JDK is installed, you can configure the system's environment variables and add the bin directory to PATH. This helps to run Java and other related tools directly from the command line.
4. Verify installation:
Open Command Prompt or PowerShell.
Enter java -version and javac -version to check the versions of the Java compiler and runtime environment.
2. Install Java Virtual Machine (JVM) on macOS:
1. Use Homebrew to install JDK (optional):
If you Using Homebrew, you can install OpenJDK by running brew install openjdk in the terminal.
2. Manually download JDK:
Visit Oracle's official website or other trusted sources.
Select the JDK version for macOS and download the installer.
3. Run the installation program:
Double-click the downloaded installation program and follow the prompts to install.
4. Verify installation:
Open the terminal.
Enter java -version and javac -version to check the versions of the Java compiler and runtime environment.
3. Install Java Virtual Machine (JVM) on Linux:
1. Use the package manager to install OpenJDK:
Most Linux distributions Each version has its own package manager that you can use to install OpenJDK. For example, on Ubuntu you can run sudo apt-get install openjdk-11-jdk.
2. Manually download JDK (optional):
Visit Oracle's official website or other trusted sources.
Select the JDK version for your Linux distribution and download the installer.
3. Run the installer or unzip the file:
The specific steps for the installer may vary depending on the distribution, or if you downloaded a compressed file, you may need to unzip and follow Related documents for configuration.
4. Verify installation:
Open the terminal.
Enter java -version and javac -version to check the versions of the Java compiler and runtime environment.
Make sure to follow the relevant documentation and tips to ensure the correct installation and configuration of the Java virtual machine.
