Java-like programming language (compiler, interpreter, debugger) with IDE that runs entirely in the browser.

The Online-IDE element accepts these arguments:

• fileList: With file list on the left.
• console: With console tab in the bottom panel.
• pCode: With PCode tab in the bottom panel.
• bottomPanel: With bottom panel.
• errorList: With error list in the bottom panel.
• height: Height of the editor. Defaults to 600px.
• speed: Speed of the execution. Defaults to 1000.
• url: The base URL of the embedded files for the Online IDE. Defaults to onlineide.openpatch.org.

````markdown A Hint
## Tip:

Tips are written in a simple Markdown syntax which
which allows **boldface** and the like, but also syntax
syntax highlighting in body text (`class square extends rectangle { }`)
and in whole paragraphs:

```

double v = Math.random()\*8 + 2; // Amount of speed between 2 and 10

double w = Math.random()*2*Math.PI; // angle between 0 and 2\*PI

vx = v \* Math.cos(w);

vy = v \* Math.sin(w);
