The following program creates a text file called test.txt and writes on it the string "some text written on a file".
import java.io.*; public class WritingOnFile { public static void main(String[] args) throws IOException { // opening the file for writing FileWriter f = new FileWriter("test.txt"); // creation of the object for writing PrintWriter out = new PrintWriter(f); // writing text on the file out.println("some text written on a file"); // closing the output channel and the file out.close(); f.close(); } }
Notes:
public static void main(String[] args) throws IOException
