Created by Charles Dang, Marius Kleppe Larnøy and Giovanni Orozco

You can either:

1. Download the ODang.jar and run it with java -jar ODang.jar
2. Download the source and run it with Maven using mvn exec:java -D exec.mainClass=ODang

Features

ODang uses a Java-like syntax, with some simplifications

Legal types: int, boolean, String, ClassType

Class Definition

class Foo {}
class Foo extends Bar {}

Class Instance Creation

Foo bar = new Foo();

int plusOne(int x) {
  return x + 1;
}

Field declarations and access

class Foo {
  int x = 2;
}
class Bar {
  Foo obj = new Foo();
  int y = obj.x + 2;
}

Limitations

• No garbage collection
