What does scanner.nextFloat() do?

• A. Reads a float value
• B. Reads a long value
• C. Reads a double value
• D. Reads an integer value

Answer: (A)

scanner.nextFloat() reads the next token from the input and converts it into a single-precision floating-point number (a float). It consumes the characters that make up that number and returns the value as a float, using the scanner’s locale to interpret the decimal separator. If the next token isn’t a valid float, it throws an exception. This is different from reading a double or an integer, which return different primitive types. So the best answer is that it reads a float value.
