You could do this by using JAVA 7 new File API.
code sample: `
public class FileWriter7 {
public static void main(String[] args) throws IOException {
List<String> lines = Arrays.asList(new String[] { "This is the content to write into file" });
String filepath = "C:/Users/Geroge/SkyDrive/Documents/inputFile.txt";
writeSmallTextFile(lines, filepath);
}
private static void writeSmallTextFile(List<String> aLines, String aFileName) throws IOException {
Path path = Paths.get(aFileName);
Files.write(path, aLines, StandardCharsets.UTF_8);
}
}

Java Write To Files
Explanation: This program tries to write some text into a file named filename.txt. If everything works, the program will print "Successfully wrote to the file." in the console. If something goes wrong (for example, the file cannot be opened), it will print "An error occurred." instead. Since Java 7, you can use try-with-resources.

Java: Save/Write String Into a File
August 4, 2020 - Since Java 11, the Files class contains a useful utility method Files.writeString(). This method comes in two variants. The most basic form requires a Path of the file to write to and the textual contents. The other variant also accepts an optional CharSet: Path path = Paths.get("output.txt"); String contents = "Hello"; try { Files.writeString(path, contents, StandardCharsets.UTF_8); } catch (IOException ex) { // Handle exception } There is little room for flexibility here, but it works great if you need to write something down into a file quickly.

November 29, 2024 - What are we doing here? The Files.write() method used here is the same as in the previous example, that is, the one that accepts an Iterable<String>. A Java 8 Stream itself is not an Iterable since you cannot iterate over it multiple times, but only once.

If you're simply outputting text, rather than any binary data, the following will work:
PrintWriter out = new PrintWriter("filename.txt");
Then, write your String to it, just like you would to any output stream:
out.println(text);
You'll need exception handling, as ever. Be sure to close the output stream when you've finished writing.
out.close()
If you are using Java 7 or later, you can use the "try-with-resources statement" which will automatically close your PrintStream when you are done with it (ie exit the block) like so:
try (PrintWriter out = new PrintWriter("filename.txt")) {
out.println(text);
}
You will still need to explicitly throw the java.io.FileNotFoundException as before.

Apache Commons IO contains some great methods for doing this, in particular FileUtils contains the following method:
static void writeStringToFile(File file, String data, Charset charset)
which allows you to write text to a file in one method call:
FileUtils.writeStringToFile(new File("test.txt"), "Hello File", Charset.forName("UTF-8"));
You might also want to consider specifying the encoding for the file as well.
