Could you give an example of what you mean by binary?
For example: text = 'A', binary = "01000001"
these are Strings or characters.
but really the binary for 'A' is x41 or as an int - decimal 65 etc
There are methods to create
String representations. See the Integer class.
Everything on a computer is in binary. The meaning a particular grouping of bytes depends on the context. The same bytes could represent a character or a machine instruction or part of an image. Depends how you use them.
