Greenfoot

Greenfoot is an integrated development environment that allows you to create Java simulations for graphics programs and games in an interactive way. The IDE provides standard Java code and combines it with a visual design and a large amount of documentation to offer a workable solution for experts and beginners alike.

For each class, you can create a subclass and customize it with a name and image from Greenfoot in the visual IDE. The app offers a large library of images that is grouped into categories such as "animals," "buildings," "objects," "people," "symbols," and more, each with a decent amount of examples.
