Saving a String to a Text File in Java

Problem:

How can you save the contents of a String variable (text) to a text file using Java?

Solution:

Using a PrintWriter

To save a String to a text file, you can use a PrintWriter object. Here's how:

1. Create a PrintWriter:

PrintWriter out = new PrintWriter("filename.txt");

2. Write the String:

out.println(text);

3. Close the PrintWriter:

out.close();

Using a try-with-resources Statement (Java 7 )

If you're using Java 7 or later, you can use the try-with-resources statement to automatically close the PrintStream when you're done:

try (PrintWriter out = new PrintWriter("filename.txt")) {
    out.println(text);
}

Handling Exceptions:

Note that both approaches require you to handle the FileNotFoundException that may be thrown when opening the file.
