Im trying to create a random character generator but I keep getting the error "Cannot instantiate the type Random" why is this?

Here is the code:

private static char randomChar(){
    Random rand = new Random(); // This is obviously the error
    char c = (char)((rand.nextInt()*26)+'a');

    return c;
}
