Quizplus · Accepted Answer

The correct method to read a floating-point number from a file is `hasNextDouble()`, which returns true if the next token in the input stream can be interpreted as a Double value. `getNextDouble()` does not exist as a method in any standard Java classes. `hasNextInt()` is used to check if the next token in the input stream can be interpreted as an int value. `peek()` is used to return the next character in the input stream without consuming it.
