My current code outputs only the first vowel it encounters. I'd like to know a way to output every vowel that is inputed once.
public static String vowels(String str) {
String vowels = "auioeëyAUIOEËY";
for(int i = 0;i < str.length();i++) {
for(int j = 0;j < str.length();j++) {
if(str.charAt(i) == vowels.charAt(j)) {
return "cointains " + vowels.charAt(j) ;
}
}
}
return "none";
}
Your inner loop should be using vowels.length() (not str.length()). You need to continue iterating and gathering the matches if you don't want to return the first vowel. You might use a Set. Something like,
public static String vowels(String str) {
String vowels = "auioeëyAUIOEËY";
Set<Character> charSet = new LinkedHashSet<>();
for (int i = 0; i < str.length(); i++) {
char ch = str.charAt(i);
for (int j = 0; j < vowels.length(); j++) {
if (vowels.charAt(j) == ch) {
charSet.add(ch);
}
}
}
if (charSet.isEmpty()) {
return "none";
}
return "contains " + charSet.stream().map(String::valueOf)
.collect(Collectors.joining(" "));
}
