Mastering Java: The Ultimate Quiz for 'Thinking in Java'

What is checked by 'hasRemaining()' method in a buffer?

1. If the buffer is empty

2. If the buffer is direct or not

3. If there are any elements between position and limit

4. If the buffer is locked

The correct answer is: If there are any elements between position and limit

The method 'hasRemaining()' checks if there are any elements between position and limit in the buffer. This method returns a boolean value which indicates whether there are any remaining elements in the buffer. Option A is incorrect because it only checks if the buffer is empty, not if there are any remaining elements. Option B is incorrect because it only checks if the buffer is direct, not if there are any remaining elements. Option D is incorrect because it checks if the buffer is locked, which is not relevant to the method 'hasRemaining()'.
