"Auto increment" alphabet in Java?

Question

"Auto increment" alphabet in Java - is this possible? From A to Z without a third-party library?

Answer 1

Yes, you can do it like this:

for (char alphabet = 'A'; alphabet <= 'Z'; alphabet++) {
    System.out.println(alphabet);
}

It is also possible with typecasting:

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

Answer 2

Yes, like this:

for (int i = 0; i < 26; i++)
{
    char upper = (char) ('A' + i);
    char lower = (char) ('a' + i);
    ...
}

Answer 3

for (char c = 'A'; c <= 'Z'; c++) {
  ...
}
