What does readByte method in FormattedMemoryInput return?

A character
An integer
A boolean
A byte

The correct answer is: A byte

The readByte method in FormattedMemoryInput returns a single byte of data from the input stream. This is different from a character (A) as a byte is a unit of data measurement while a character is a symbol from a set of symbols used to represent things like letters and numbers. An integer (B) is also a unit of data measurement, but it is typically larger than a byte and used to represent whole numbers. A boolean (C) is a data type with a value of either true or false and is not relevant to the readByte method. Therefore, the correct answer is D A byte.
