I have already written an autotalker in C#. But a friend asked me to
make one for Mac so I decided to do it in Java. I can't even work out
the error. Can someone please tell me how to fix this.
Here is my code:

When reporting an error, you should copy and paste the error message into your
post. I am guessing that you found that the line
keyInput[n] = myChar.getKeyChar();
didn't compile.

'myChar' is of type 'char', which is a primitive. Therefore you cannot invoke
a method on 'myChar'.

To invoke an instance method like 'getKeyChar()', you must have a variable of
a type that has such a method. I note that the wrapper class 'Character' has
no such method either.

Review
<http://java.sun.com/docs/books/tutorial/index.html>
and
<http://java.sun.com/developer/onlineTraining/Programming/BasicJava1/>

package messengerspam;
// import ...; // imports elided for brevity

public class Main {

public static int keyInput[];

This is fine for an example. For real-life code you should tend toward
private instance variables rather than public static ones.

    public static void main(String[] args) throws
AWTException,IOException {
        InputStreamReader isr = new InputStreamReader( System.in );
        BufferedReader stdin = new BufferedReader( isr );
        String input = stdin.readLine();

        char[] splitin = input.toCharArray();

        int n = 0;
        for (char myChar : splitin)
        {
            keyInput[n] = myChar.getKeyChar();

            n = n + 1;
        }
        keyInput[n] = KeyEvent.VK_ENTER;

        Robot robot = new Robot();

        for (int i = 1; i > 1; i++){

Interesting idiom. This loop will never run.

            for (int t = 0; t < keyInput.length; t++){
            robot.keyPress(keyInput[t]);
            }
            robot.delay(500);
        }
    }
}
