What is the Difference between float "1" and float "1f" in Java?

Question

Is there any difference - in Java - between defining float variables like, e.g., this: 1 and this: 1f? Is the JVM doing any casts at run-time when I write 1, or something that could slow down my app?

Regards

Answer 1

1 is implicitly considered as int literal where 1f is considered as float literal
