It is fine that the println method of PrintStream is overloaded for each primitive types and also the Object reference. But why do we need another overloaded println method for String when we already have one for Object ? I understand that String is an Object in Java.
Doesn’t
void println(Object x)
make
void println(String x)
unnecessary ?

There is a call x.toString() in println(Object x) that is not needed in println(String x)
A little speed gain, or for completeness?


SCJP2. Please Indent your code using UBB Code
 
It is sorta covered in the JavaRanch Style Guide.
