This page lets you paste markdown that includes Java, see it rendered with Java syntax highlighting alongside the text, and share the result through a read-only link.
Java tends to appear in markdown that explains a decision or teaches something. A senior engineer writes up why a service class should be split before the change is opened for review. An onboarding doc walks a new hire through the request flow of a Spring application, one annotated controller at a time. Instructors hand out exercises with a starter class and a short list of requirements, and students send back notes on what they tried. In each case the reader needs to see the class structure clearly, and Java’s verbosity makes that hard in a plain text box.
The rendered view separates annotations, modifiers, type names, string literals and comments by color, while headings, numbered steps and tables around the code take their normal formatting. A table of contents appears automatically once the document has three or more headings, which helps with longer walkthroughs.
There is no compiler or JVM here; the code is only displayed, so it is up to the reader to build and test it. Sharing produces a link that works without signing up, and the document is deleted automatically 15 days later. Students and reviewers can open it on a phone too, where the Preview view shows the rendered document full width.
How to view Java in markdown
- Paste your markdown into the editor above, or edit the example.
- Wrap Java code in a fenced block that starts with ```java.
- The preview shows the rendered document with the code highlighted (side by side on desktop; switch to Preview on a phone).
- Select Share to get a read-only link that anyone can open without an account.
Frequently asked questions
Are annotations like @Override highlighted?
The Java grammar used by the highlighter (highlight.js) recognizes annotations, keywords, types, strings and comments, so an annotated class reads with those parts in different colors. The ```java tag is the one to use.
Can I compile or run the Java code from the page?
No. The viewer has no compiler or runtime. It is meant for reading and sharing; build the code in your own environment.
Is Kotlin or Scala highlighted too?
No. Only 13 languages are highlighted, and Kotlin and Scala are not among them. Their code blocks still appear, in plain monospaced text.
