Question

Given a FILENAME constant that specifies a valid filename for a file, which statement can you use to get a stream to write data to that file?

Answer 1

To write data to a file specified by a FILENAME constant, use a FileWriter object in Java. The code to create it would be `FileWriter writer = new FileWriter(FILENAME);`. Handle exceptions properly and close the stream after use.

Step-by-step explanation:

To get a stream to write data to a file specified by a FILENAME constant, you can use the FileWriter class in Java, for example. The statement to create a FileWriter object would look something like this:

FileWriter writer = new FileWriter(FILENAME);

This will give you a writable stream, allowing you to write text data to the file represented by FILENAME. If you need more control over how the data is written, or if you want to write binary data, you would instead use a FileOutputStream.

Remember to handle exceptions that may occur when working with file I/O such as IOException. Always ensure that you close the file stream properly by using a try-with-resources statement or calling the close() method in a finally block.
