Thank you for your explaination. I think this solution is much simpler:

public static char firstNonRepeatedChar(String str) {
for(int i = 0; i < str.length() - 1; i++) {
if &&
!(str.substring(0, i).contains(str.charAt(i) + ""))) {
return str.charAt(i);
}
}
throw new RuntimeException("No non repeated char was found.");
}
