Java Language Tutorial => Writing a file using PrintStream

Example

We can use PrintStream class to write a file. It has several methods that let you print any data type values. println() method appends a new line. Once we are done printing, we have to flush the PrintStream.

import java.io.FileNotFoundException;
import java.io.PrintStream;
import java.time.LocalDate;

public class FileWritingDemo {
    public static void main(String[] args) {
        String destination = "file1.txt";

        try(PrintStream ps = new PrintStream(destination)){
            ps.println("Stackoverflow documentation seems fun.");
            ps.println();
            ps.println("I love Java!");
            ps.printf("Today is: %1$tm/%1$td/%1$tY", LocalDate.now());

            ps.flush();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }

    }
}
