public static void main(String[] args) {

String s1 = "aaabbccccaaa";
String s2 = " ";
for (int i = 0; i < s1.length(); i++) {
if (i == 0) {
s2 = s2.concat("" + (s1.charAt(i)));
}

if (s2.contains(s1.charAt(i) + "")) {
continue;
} else {
s2 = s2.concat("" + (s1.charAt(i)));
}
}
System.out.println(s2);
}
