Java typing practice

Java makes you type more than almost any mainstream language: full class declarations, access modifiers, types on everything, and a semicolon at the end of every statement.

CodeTrained's Java path is 18 exercises of real, runnable Java — typed by hand, one line at a time, with live speed and accuracy feedback.
