Which of these method of FileReader class is used to read characters from a file?Optionsscanf()read()get()getInteger()

Identifying the Correct Method

To determine which method of the FileReader class is used to read characters from a file, let’s analyze the provided options in the context of Java's FileReader class:

1. scanf() - This is not a method of the FileReader class. It is a function used in C/C++ for formatted input.

2. read() - This is indeed a method of the FileReader class. It is used to read a single character or an array of characters from a file.

3. get() - While there may be a get in other contexts, it is not a defined method in the FileReader class.

4. getInteger() - This method does not exist in the FileReader class; it seems to be more relevant to getting primitive types rather than reading character data from files.

Final Answer

The method used to read characters from a file in the FileReader class is read().
