What adapter must i use to make a projection of an m4v-file (sound and images)

Question

I have to make a presentation from an m4v-file. What adapters shall i use for sound?

Answer 1

PrintStream doesn't like the FileWriter, it's all squiggly. Oh, and I found the right event so that it updates every time i type a letter. So, what is this you say about making a FileOutputStream an attribute? I don't know what that means. I'm also not sure what you mean by listener, is that the PrintStream?
private void jTextPane1KeyTyped(java.awt.event.KeyEvent evt) {
FileWriter out;
PrintStream p;
try
out = new FileWriter("myfile.txt");
p = new PrintStream(out);
p.println (jTextPane1.getText());
p.close();
catch (Exception e)
System.err.println ("Error writing to file");}
}
