Alternate Statements of System.out.println()

Question

Can anybody please help me by providing different ways of printing other than System.out.println() statement in Java?

But still printing to stdout? Why are you trying to avoid System.out.println? — Jon Skeet, May 10 '11 at 05:31
I just want to learn the different ways.Is it possible to use a file? — hari, May 10 '11 at 05:34
You can read/write to a file (including properties files) but that is an unrelated question really. — Peter Lawrey, May 10 '11 at 07:46

import org.apache.log4j.Logger;
....
public class example{

static Logger log = Logger.getLogger(this.class);

.....
public void test(){
 String hello ="Hello World";
 log.trace(hello);
}
....
}

output will be :
TRACE:(<classname>){2011-10-38-06:644} Hello World 2011-05-10 08:38:06,644

It should be noted that, for this to work, your project has a dependency on Log4j, and `log4j.properties` has to be properly configured. – darioo May 10 '11 at 05:53
you must add log4j-1.2.14.jar to your project if you can't find this jar file, type your email here i will send it to your email – Georgian Citizen May 10 '11 at 07:28

This may help you.

import java.io.*;
class Redirection {
    public static void main(String args[]) throws IOException {
        PrintStream pos = new PrintStream(new FileOutputStream("applic.log"));

        PrintStream oldstream=System.out;
        System.out.println("Message 1 appears on console");
        System.setOut(pos);                 
        System.out.println("Message 2 appears on file"); 
        System.out.println("Message 3 appears on file");
        System.out.println("Message 4 appears on file");
        System.setOut(oldstream);
        System.out.println("Message 5 appears on console");
        System.out.println("Message 6 appears on console");        
    }
}

Alternate printing methods:

System.out.print("message\r\n");
System.out.printf("%s %d", "message" , 101); // Since 1.5

You can also use regular IO File operations by using special files based on the platform to output stuff on the console:

PrintWriter pw = new PrintWriter("con"); // Windows
PrintWriter pw = new PrintWriter("/dev/tty"); // *nix

pw.println("op");

System.err.println() for printing on console. or create your own printstream object and then print to file, database or console.

You can try the following alternatives:

1.

System.err.print("Custom Error Message");

2.

System.console().writer().println("Hello World");

3.

System.out.write("www.stackoverflow.com \n".getBytes());

4.

System.out.format("%s", "www.stackoverflow.com \n");

5.

PrintStream myout = new PrintStream(new FileOutputStream(FileDescriptor.out));
myout.print("www.stackoverflow.com \n");
