Answer 1

you can use random UUIDs...

Example:

final String randomCode = UUID.randomUUID().toString();
// or you can play with the len...
final String randomCode2 = UUID.randomUUID().toString().substring(0, 5);

Answer 2

You can use apache commons-lang RandomStringUtils.randomAlphanumberic:

"ADF18" + RandomStringUtils.randomAlphanumberic(5);
