Question about data types
I was studying about data types in Java, I have some basic questions
what is the meaning of default value for a data type?! what's the use of it?
default value of int is 0
default value of long is 0L
default value of float is 0.0f
default value of reference data type is null
what's the difference between bit and byte?! is bit a data type as well?
what's the difference between float and double?
the minimum value of character is \uoooo, and the max is \ufffff....what are these symbols?! aren't characters only a,b,c....?
thanks much already
