-=====Integrated Development Environment=====+=====Java-Editor=====
  
 Integrated Java development environments set high requirements on the computer equipment. These requirements are not always met in schools. If the students shall work at home with these development systems, only freely available systems come into question. There are hardly any systems left which actually can be used for teaching. This was the reason for me to develop the Java-Editor which is described below. Integrated Java development environments set high requirements on the computer equipment.

 + 
 +==== Puzzle mode ==== 
 +The puzzle mode allows you to create interactive structogram puzzles, in which the students create a complete structogram from puzzle pieces. To create a structogram puzzle, start with the solution, which must consist of a single algorithm-structogram. To do this, call up the puzzle mode in the context menu of the structogram. 
 + 
 +Extract the structogram elements from the complete structogram, leaving the original space as an empty placeholder. 
 + 
 +{{:en:puzzleeasy.png}} 
 + 
 +The puzzle elements retain the original shape in width and height. When puzzleed together puzzle pieces fit only if they are the right size. Save the structogram puzzle in this version. It will then appear three more puzzles and distinguished by //easy//, //medium//, //hard// and //very hard//. You can still rework them. 
 + 
 +In medium mode, the height of the puzzle pieces is reduced to the standard height. 
 + 
 +{{:en:puzzlemedium.png}} 
 + 
 +You can push puzzle pieces into empty structogram elements or place them between existing structogram elements. It is no longer the height, but only the width controlled. Only if this fits the insertion point, a puzzle piece can be inserted there. One can increase the difficulty by removing some structogram elements in sequences of empty structogram elements.  
 + 
 +In //hard// mode, in addition to the height, the width of the structogram elements is also reduced to the standard size. 
 + 
 +{{:en:puzzlehard.png}} 
 + 
 +Puzzle pieces can now be inserted at any position, neither width nor height must fit.  
 +In //very hard// mode, as far as possible, empty structogram elements are also removed. 
 + 
 +The students can choose a suitable puzzle variant in the classroom. If they have created a solution, they can independently check it by clicking the puzzle button {{:en:puzzlebutton.png}} . The Java-Editor tells if the solution is found or something needs to be changed. 
 + 
 +When switching to puzzle mode, the complete solution must be in a single structogram. From this solution, the Java-Editor remembers a text representation and compares it with the text representation of the student solution. 
 + 
 +If sequence order does not matter in two successive instructions, a solution with a reversed order is also correct in terms of content. This can not be controlled by the Java-Editor. Therefore, one should not take apart the two puzzle pieces in such cases. 
 + 
 + 
 +===== Sequence Diagram ===== 
 + 
 +The Sequence Diagram tool lets you interactively create a sequence diagram. Lifelines exist in two forms, as an actor and with a named head. They are inserted using the toolbar. To create a connection between lifelines, use  //connect to// from the context menu of a lifeline. To change texts call the text editor with a double-click. 
 + 
 +{{:de:sequenzdiagramm.png}} 
 + 
 +You can display a debugger session as a sequence diagram via the // Test / Create Sequence Diagram // menu. 
 +The same applies to work without or with debugger in a UML window.
