Java import does not affect if a class is available (*)
it is just a compile time convenience feature.

(*) a 3rd party library (jar) needs to be put in the classpath for the
classes it contains to be available.


You don't have to use import - you can write out the path explicitly in
your source code.


java.text.DecimalFormat fmt = new java.text.DecimalFormat("0.0");


When compiled, the bytecode this produces will be indistinguishable from
the bytecode produced for


import java.text.DecimalFormat;

DecimalFormat fmt = new DecimalFormat("0.0");

No.

Import them explicitly.
