Java typing practice
Type Java faster where it actually hurts: braces, semicolons, generics and long keyword chains. Start typing below - no sign-up.

What makes code typing different
General typing trainers drill prose, where letters dominate. In code, symbols and casing carry much of the load. CodeKeys measures every key, symbol cluster and keyword, finds the weakest one, and generates practice that looks like the language while drilling your weak spots.
Symbols, not prose
Practise ();, ) {, ->, :: and <> - the transitions where code typing stalls.
Adapts to you
Every key and symbol is timed; your weakest one fills the next lesson until it reaches your target speed.
Real Java
Drills follow Google Java Style, and real snippets cover records, streams, generics and exceptions.
