Need help with simple program

I need to make a program that displays each char value from a to z, basically listing the alphabet. How exactly would I do this? Should I use the for() method until I reach z?

each character has a numeric representation...if i'm not mistaken, A=65, B=66, ... Z=90, so you can have a for loop from 65 to 90, casting these ints into chars....

Code:

---

                for(int i=65;i<=90;i++) {
                        System.out.println((char)i);
                }

---

ps. these would print the characters in uppercase letters, look for an ASCII table to see their representation in lowecase.
