    }
}

which of the following definitions can be added to it so that it successfully compiles?

long Byte = 0;
long byte = 0;
long Char = 0;
long char = 0;

Explanation

Java language keywords such as names of primitive types like byte and char cannot be used as variable names.
Default library class names such as String, Byte, and Char are not considered to be keywords and may be used as variable names.
The string identifier is not a Java keyword and can also be used as a variable name.
