Wo ist der unterschied javaeditor und processing

Also ich Tip mal drauf das er -O nicht kennt. Ich denke mal der komische Editor kompiiliert mit irgendwelchen dubiosen Parametern. Schon mal versucht die Java Datei in der Console händisch zu compiliere?

Evtl. Mit Eclipse oder Netbeans

Was für ein JDK haste denn installiert? Der Sun-Compiler akzeptiert "-O"...

Nee, macht er nicht. Um kleine Klassen und Beispiele zu testen nehme ich auch den Java-Editor. Bei mir siehts in der Einstellung so aus:

Jikes hab ich hier nicht installiert, deshalb ist der Eintrag rot markiert.

Javah hat als einzige den Parameter -O (Output)

Nö. javac unterstützt den noch, ohne zu motzen. Früher hat das die Optimierung eingeschaltet, heute ist's nur noch ein Dummy, AFAIK.

Hints after video one. This may never be seen?

For example, you could make a self-portrait, an alien creature, or something more abstract. It'll just be black and white for now, we'll get to color in the next video.

You can work on your own pace, but we recommend approximately ten minutes on this assignment before moving on.

Reminders
To draw a rectangle: rect(a,b,c,d);
To draw an ellipse: ellipse(a,b,c,d);

a — X (horizontal) location of the shape's upper-left corner

For more, check out the rectangle and ellipse pages on processing.org.

You can build off the example below or add to your previous design by selecting "My Code from Last Lesson" under the "Code" menu below.

You can work on your own pace, but we recommend approximately ten minutes on this assignment before moving on.

Reminders
Set the background color: background(r,g,b);
Set the outline color: stroke(r,g,b);
Set the interior color: fill(r,g,b);

Don't forget, you need to call stroke() and fill() before you draw the shape!

r — amount of red, from 0 (none) to 255 (maximum)

For more, check out the background, stroke and fill pages on processing.org.

If you forget the syntax for setup() and draw(), here is a reminder!

We recommend a maximum canvas size of 500 by 400 pixels for this tutorial, but feel free to experiment your window skinnier or shorter!

Here is an example of drawing a different color depending on whether the mouse is pressed.

You could also consider drawing the background only when the mouse is pressed. For example:

rect(250, 200, 150, 100);

rect(250, 200, 150, 100); rect(50, 80, 40, 25);

rect(250, 200, 150, 100); rect(50, 80, 40, 25); rect(400, 10, 15, 100);

rect(250, 200, 150, 100);

rect(250, 200, 150, 100); ellipse(250,200,200,200);

ellipse(250,200,200,200); rect(250, 200, 150, 100);

rect(250,200,100,75);

stroke(0); rect(250,200,100,75);

stroke(0); fill(128); rect(250,200,100,75);

stroke(255,0,0); fill(128); rect(250,200,100,75);

stroke(255,0,0); fill(0,0,255); rect(250,200,100,75);

background(216,225,149); stroke(255,0,0); fill(0,0,255); rect(250,200,100,75);
