There are a few ways.  I prefer to use Math.random().  Math is in java.lang so you don't need to import it and random is a static method so you don't need an instance of the class. It returns a double between 0.0 and 1.0. To get an integer from 1-6 you would use:
java:die = (int)(Math.random() * 6 + 1)

Why does everone spell my name wrong?

In Java a character is just it's ascii value. So for example:
System.out.println((char)67);
will print C
So now just randomly generate your numbers in the ascii range you need:
A-Z == 65-90
a-z == 97-122
