Java program to remove duplicates characters from given String.
class RemoveDuplicate {
public static void main(String args[]) {
remove("123aa bbbcc c2589 99oppq rtyyy");
}
static void remove(String s) {
int l = s.length();
int c;
String org = s, s1 = "";
for (int i = 0; i < (l - 1); i++) {
s1 = s.substring(0, i + 1);
c = 0;
for (int j = i + 1; j < l; j++) {
if (s.charAt(i) == s.charAt(j)) {
c++;
continue;
} else
s1 = s1 + s.charAt(j);
}
s = s1;
s1 = "";
if (c > 0)
l -= c;
}
System.out.println("Original String:" + org);
System.out.println("String after removing duplicates: " + s);
}
}
Output:
Original String:123aa bbbcc c2589 99oppq rtyyy
String after removing duplicates: 123a bc589opqrty
