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.

Open Java Settings

1. Open the Code Editor Plugin.
2. Open any Java code file.
3. Click the Settings icon in the editor header.
4. The Java Configuration dialog will open.
5. Configure the required Java settings and click Save.

Configure Java Home

Java Home Path specifies the location of your JDK installation.

macOS

Run the following command in Terminal:

/usr/libexec/java_home

Copy the output and paste it into the Java Home Path field.

Windows

Run:

where java

Locate your JDK installation and provide the corresponding Java Home directory.

Linux

Run:

which java

or

readlink -f $(which java)

Locate your JDK installation and provide the Java Home directory.

Configure Main Class

Enter the default Java class name that should be executed when your code does not explicitly specify one.

Default Value

Main

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.
