Java Random Letters

FirstAttempt.java

package test;
     
public class Test {
    private static String alphabet = "abcdefghijklmnopqrstuvwxyz";
    public static void main(args[]) { //haven't written main in awhile... pretty sure this is wrong

      int limit = 100; //hard coding since I dont remember how to work with args
      int iteration = 3; //every third number
      int count = iteratin;
      for(int i = 0; i < limit; i++) {
        count--;
        if(0 >= count) {
          count = iteration;
          //oh hell...
          int r = (int)(Math.random() * 26); //forgot how to get a random number!
          String c = Test.alphabet.substr(r, r+1); //I want to cut out that one letter... right??
          System.out.println(c);
        }
      }
    }
