How do i create random strings?

[Andrew Stevens]

I need a no paramater constructor that generates a random 4 letter string. Is there a way to do this using Math.random?

[Junilu Lacar]

char randomLetter = (char)('A' + (Math.random() * 26));
I'm leaving the rest for you to figure out just in case this is a school assignment

You could create a collection of the 26 characters, shuffle the Collection and select four elements.
