Answer 1

Martin Taylor wow, you put so much effort to do this. Like you write those big copywrite stuff and other information. Tnx for answer =) I noted all

Answer 2

1. You can get a character from a String with "string".charAt(index);
2. The .contains() method however needs another String so you can either think of a way to give it a String maybe with .substring(index, index + 1) or you can change your vowels to an int array[127] and use the vowel characters as indexes.
int array[] vowels = new int[127];
vowels['a']++;
vowels['e']++
vowels['i']++;
etc...
then in your for loop (which by the way is missing it's break condition so you need to add it maybe check the longest string's lenght) you can use
if (vowels[s1.charAt(i)] > 0) {
++vowels_s1;
}
