Source code as output

Question

hello everybody,
This is my post to this forum.
My question is "How to print the soource code as output"? Is there any method to echo the same code as output?
Thanks in advance.

What about this?Well, that requires that you have to source of the
class in the current directory. I think (but I might
be wrong) that the OP wants to write a class which
prints itself without using the source.
Kaj...but if the OP has control over the source itself it's better to get hold of the source as a resource instead of a file. Simply bundle the source code with your classes on the classpath. Or better yet, put it in your jar.
I think the jdk/demo/jfc/SwingSet2 demo does something like this when showing each example's source under the "Source Code" tabs...
Example:
package example;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.PrintStream;
public class Source {
    public static void print(Class clazz, PrintStream printStream)
            throws IOException {
        // convert from "example.Source" to "/example/Source.java"
        String resourceName =
            "/" + clazz.getName().replaceAll("\\.", "/") + ".java";
        InputStream inputStream = clazz.getResourceAsStream(resourceName);
        if (inputStream == null) {
            printStream.println("no source found for class " + clazz.getName());
        } else {
            BufferedReader reader =
                new BufferedReader(new InputStreamReader(inputStream));
            String line;
            while ((line = reader.readLine()) != null) {
                printStream.println(line);
    public static void main(String[] args) throws IOException {
        // example usage: print the source of class Source on System.out
        Source.print(Source.class, System.out);
