Then press the Start Jai button on the left side in this page, below the duke icon. After a few seconds or more, you should get a new frame Figure 2. If the new frame does not show up, get help in FAQ.

Follow the instruction in the new frame. The word JLS references a chapter in the Java Language Specification.

Try to modify all examples and make the test at the end of a level.
