The thing is, I’m creating an android app and I prescribe shuffle the value of a string.
Example:
String name = "Bruno";
Shuffles the string value(name).
Output: "ronub"

This function will solve:
public static String shuffle(String text) {
Random random = new Random();
List<Character> collect = text.chars().mapToObj(c -> (char) c).collect(Collectors.toList());
List<Character> newList = new ArrayList<>();
while (collect.size() > 0) {
Character character = collect.remove(random.nextInt(collect.size()));
newList.add(character);
}
StringBuilder sb = new StringBuilder();
for (Character c : newList) {
sb.append(c);
}
return sb.toString();
}
for example 10 times with my name "Thiago Born" and the results were:
oTaon hgBri
onogBirTh a
r iaghoTBno
ronBTgiao h
BigTo hanro
