@TomBredemeier That’s a bold claim! Show me! 😏

Year 12 Computer Science students have been getting to grips with Object-Oriented Programming concepts recently and have been creating a farming simulation in @BlueJ_IDE

Great tip!

This is your annual reminder that if you type for loops on three separate lines in @BlueJ_IDE, the debugger will highlight each of the three parts individually. This visualization is a huge help for students as they explore this unexpected flow of execution.

@Herr_Rau Perhaps a chance for further improvement? Selecting text before typing { surrounds the text with parentheses?

Did you know: A small but useful improvement in BlueJ's Java editor, added in version 5:
When you enter an opening { the closing } is now automatically added as well.

(Pro tip: Or you could just use Stride – no more missing brackets ever...)

BlueJ 5.0.2 has been released this week. A small bug fix release.

At the home of the BlueJ.

Did you know: You can open classes in separate windows by shift-double-clicking.
And since v5.0.1, BlueJ will remember your previous window positions and sizes and reuse them.
So you can prepare code windows and open them easily side-by-side to discuss with your students.

Raving review: "quite good". :-)

[BlueJ - The Educational Java IDE @BlueJ_IDE]

@iamsoumyacr @omarsar0 We think so!

BlueJ with JavaFX?
Simon Gebert recently wrote a new BlueJ extension to integrate using SceneBuilder into your BlueJ workflow.

In version 5, BlueJ received a new, improved extensions API.
Several extensions have now been released that work with the new API (and thus with BlueJ 5).

See them here: https://t.co/YSxFhWktK4

Did you know: with BlueJ 5.0.1, extensions can now handle external files. If an extension is installed that can handle a file type, the file is shown in the diagram, and the extension can open an external editor.

[BlueJ - The Educational Java IDE @BlueJ_IDE]

In version 5.0, BlueJ received an entirely new editor implementation (improved again in 5.0.1).

Looking similar to before, but much faster and more robust (completely rewritten by @neilccbrown).

Try it out if you haven't already!

We're alive!

About 22 years after BlueJ was first released, we now have a Twitter account.

Always at the cutting edge of technology.
