Pico Compiler is the first offline Java 9 compiler available in the App Store!

Pico Compiler is a lightweight development environment for writing Java programs.

Key features:

• Java 9 offline compiler

• Developer keyboard - Developer keyboard adds a new row of keys to the default on-screen keyboard. It consists of swipe buttons with all common symbols, punctuation and brackets, and a special navigation key.

• Smart code completion - Pico will complete the names of classes, methods, fields, and keywords within the visibility scope. When you invoke code completion, Pico Compiler analyses the context and suggests the choices that are reachable from the current position of the caret.

The app is designed as an educational tool and cannot be used to develop complex projects (Spring, Hibernate, Java EE etc). Visit project website at https://www.marcinolawski.pl/pico/ to learn all Pico features and limitations.

Good Potential, but still missing adding java files

Re-downloaded it and bought the 2.99 pro version. You can make things from scratch -which is a good for practice. But there is a missing feature to add and remove files, to transfer files to computer.

Nice for some experimental coding

Very nice app for experimenting and exploring ideas while away from the PC; very useful for when I am waiting in line somewhere, and an idea pops into my head. The free version is just to give you an idea of how it works, and the price if the pro version is good considering what one can do with this app. Highly recommended!

Free version is useless

Simple interface and very functional.

I used to recommend this to my students as an on-the-go compiler. Supports imports and Scanner inputs.

Wouldn’t mind a scaled-down app without imports or something in the free version but as it stands, files can’t be edited at all. It’s just a proof of concept for “hello world” to sell you on the Pro Version. Would happily pay for a “Pro” version if I could still recommend the free version to my young coders.
