Get started
- Create a note and choose Java, or import a .java file.
- Edit the source, search for a symbol, or insert a built-in snippet.
- Compare a revision in the split panes when needed.
- Download the source and check it in your JVM environment.
Open editor takes you to the draft on this page. Paste or open a source file, or choose Try this example. Save to notebook keeps a named copy with your notes. Your workspace style stays unchanged.
public class Ready {
public static void main(String[] args) {
System.out.println("Ready for review");
}
}Edit, compare, and keep reusable source
Import .java source or choose Java in the searchable language chooser. Use find and replace, line numbers, comment toggling, and comparison panes to review changes. Save a useful selection as a snippet or start with a built-in example.
Source highlighting uses a lightweight language mode. Large documents use background highlighting; this is syntax coloring rather than a compiler or full language service.
Run and check code in your JVM environment
The notebook does not execute Java, resolve dependencies, or compile a project. Formatting and minification are unavailable for this mode, so source text stays under your control.
Download the .java source to run it in your own JVM environment. Local notes do not synchronize between devices; export a backup to keep a separate copy.
A few questions
Does this run Java code?
No. It edits and highlights source. Use your own JVM environment to run, compile, and validate it.
Can I edit offline?
Yes, after initial online setup shows Ready to use offline. Notes remain in this browser on this device.
