SnapCode - a real Java IDE for the Web

Overview

SnapCode makes it fast and easy to start coding Java in any modern browser. SnapCode offers modern coding features, support for Java REPL (Read-Eval-Print-Loop), and full featured library support for UI, graphics, charting, 3D and more. All of this makes SnapCode effective for a broad range of uses from education to engineering and data science.

SnapCode gets things started quickly with these features:

No install - runs in browser (Click here to run)
Java REPL coding - just start coding (no class/main-method boilerplate needed)
REPL style output (shows stacked output as rich interactive views)
Integrated UI builder
Integrated help system
Block coding support
Project level search (strings or symbols, references and declarations)
Integrated developer tools
Support for 'Share' links to easily share code
Desktop app: Download Page

Modern IDE Features

SnapCode has everything you expect from a modern IDE to make writing code fast and easy:

Syntax highlighting
Code completion (receiving class/type aware)
Matching symbol highlighting
Balanced character pair handling for parens/brackets
Inline as-you-type warnings and errors
One click jump to symbol declaration, super declarations, JavaDocs and source
Editor shows the AST hierarchy of selected symbol

Java REPL (Read-Eval-Print-Loop)

SnapCode allows you to avoid boilerplate code and evaluates code snippets as you type for instant feedback.

Implicit Class and main method declarations - just start typing code
Variable type 'var' for implicit variable type declaration
Statement terminators (semi-colons) are optional
Direct access to common System methods without preamble (print(), println(), etc.)

Java REPL support is optional - full Java is supported, and can be auto-generated, for when code needs to be portable and compliant.

Full Featured Library Support

SnapCode is built using the SnapKit and SnapCharts libraries giving access to advanced application features.

Integrated UI Builder

Because the best line of code is the one you don't have to write, UI is almost always created using the with the integrated UI builder and stored in simple XML files ('.snp' files). Simply create/save a .snp file with the same name as your custom controller class, and the default controller.createUI() method will load it.
