append a char to a JTextArea

So I'm working on making a class that will "type" letters into a JTextArea, pausing between each letter to make it look like someone is typing. The only way I can come up with is using output.append(char) in a loop with a pause. The only problem... you can only append Strings to JTextAreas.

So is there any way to convert a char to a string so that I can append it letter by letter???

Here is my code so far:

import objectdraw.*; import java.awt.*; import javax.swing.*; public class TypeWriter extends ActiveObject implements Drawable { private char [] letter; private JTextArea cp; public TypeWriter(String sentence, JTextArea console) { /* break string into characters and save the console * for later use */ letter = new char[sentence.length()]; cp = console; for(int i=0; i<sentence.length(); i++) { letter[i] = sentence.charAt(i); } start(); } public void run() { // append each letter, pausing between them for( char s : letter ) { cp.append(new String(s)); pause(50); } } /* More methods for the * Drawable interface... */ }

-------------Problems Reply------------

Don't use characters.

String foo = "This is a String";
for (int i = 0; i < foo.length(); i++)
{
String subString = foo.substring(i, i+1);
cp.append(subString);
pause(50);
}

Use the String(char[] value) constructor so

String s = "";
s += Character.toString('s');
