Type Matcher
Match each value to its Java data type — how fast can you go?
A Java value will appear on screen. Click the button for its correct data type. You'll see 20 values — answer as quickly and accurately as you can!
What type is this value?
Tip: Pay close attention to suffixes like L for long and f for float. A number with a decimal point (like 3.14) defaults to double in Java, not float!
