To execute Java programs in the Code Plugin, Java must be installed on your local machine. DevScribe uses your local Java installation to compile and run Java code.

---

Prerequisites

Before configuring Java in DevScribe:

• Install a Java Development Kit (JDK) on your machine.
• Verify the installation by running the following command in your terminal:

java -version

If Java is installed correctly, the installed version will be displayed.

Note: DevScribe uses your local Java runtime and compiler. It does not include a bundled JDK or JVM.

Additional JVM Arguments

You can optionally provide additional arguments that will be passed to the Java Virtual Machine (JVM) when your program executes.

Example:

-Xmx512m -Xms256m

These options configure the maximum and initial heap memory available to your Java application.

Save Configuration

After filling in the required fields, click Save. Your Java environment is now configured and you can start writing, compiling, and running Java programs directly from the Code Plugin.
