JAVA Q2: Write a program that reads strings from the user and writes them to an output file called userStrings.txt. Stop processing when the user enters the string \"DONE\". Do not write the sentinel string (\"DONE\") to the output file. [15 points] Hint: For a complete example of file IO, please see the attached TestData program. Sample Output: A string. Another string.

Q2: Write a program that reads strings from the user and writes them to an output file called
userStrings.txt. Stop processing when the user enters the string "DONE". Do not write the
sentinel string ("DONE") to the output file. [15 points] Hint: For a complete example of file IO,
please see the attached TestData program.
Sample Output:
A string.
Another string.
Yet more text...
DONE
Solution
Answer
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Scanner;
class WriteStringFile {
public static void main(String[] args) {
File file = new File("D:/userFile.txt");
String data;

2. Scanner input = new Scanner(System.in);
data = input.readLine();
try (FileOutputStream fop = new FileOutputStream(file)) {
// if file doesn't exists, then create it
if (!file.exists()) {
file.createNewFile();
}
if (data != "DONE") {
// get the content in bytes
byte[] contentInBytes = content.getBytes();
fop.write(contentInBytes);
fop.flush();
fop.close();
} else {
System.out.println("User Enter the value Done.. So unable to write into file");
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
