IDE Amadeus_AlgJava

Download

Amadeus_AlgJava provides beginners with extremely simple tools  for  practical exercises  in  algorithmic programming  techniques and concepts. The main principles are simplicity and similarity to Java.

Operating systems: Windows, Linux, SunOS.
Minimal user interface -- less than 50 elementary menu items.
User interface language -- Estonian, Russian, English.
Clear notion of project.
Work: under projects.
Programming language -- AlgJava:
 every program is included in a predefined Java class. The users do not write their own class definitions.
However, the users may  apply  methods from Java API classes and even instantiate them.
Base tool -- Java 1.6
Editing: structural statements and method definitions are created as complete templates. 
Simplifications compared to Java:
   the main part of the user's program is considered  the  main method of the class  Main,
       the user does not write the typical code fragments
       class Main {
         public static void main (String[] args) {

         }
       }
       those are included by default;
   the main part of the user program is followed by definitions of static methods (if any),
       the user needs not use the modifier  static,  as it is included by default;     
   the following features are optional:
      method calls print[ln](_);    instead of      System.out.print[ln](_);
      an additional method   String readln() for  console input
      the loop head  i = a .. b instead of  for(int i = a; i <= b; i++)
      a JFrame containing a JPanel for simple screen graphics (the frame is created behind the scene)
an additional method for opening a text file reader
BufferedReader readerFrom(String fileName)
an additional method for opening a text file writer
PrintWriter writerTo(String fileName)
break point statements, allowing to inspect the current values of variables, expression and arrays at the break

Example
The "famous" hello-world program  in AlgJava consists of the single line:
println("Hello, world!");

Additional features

A primary set of  macros, which can be extended by users.

Error  diagnostics -- localization at the source (AlgJava) level,
             description (in English) as  error output from javac.

Demo programs (in AlgJava) belong to the project AlgJavaDemo and are downloaded together with the IDE.
