Writing Out a Basic Text File
The below command line program demonstrates use of a FileWriter to create a text file and write out text data into it.

package ceccs;
import java.io.File;
import java.io.FileWriter;
public class Main {
public static void main(String[] args) {
String msg = "Here's some text that you wanna save safely!\nYay!";
String fileName = "test_file.txt";
File file = new File(fileName);
try {
if (file.exists() == false) file.createNewFile();
FileWriter fw = new FileWriter(file);
fw.write(msg);
fw.close();
} catch (Exception ex) {
System.out.println(ex);
}
}
