Remove common characters from given strings

• We can remove common characters from given strings using for loops and string replace method.

Example:

1) s1 = abc@ , s2 = cd@e

Modified s1 = ab,  Modified s2 = de

If you notice above example  ‘c’ and ‘@’ were common characters and both have been deleted from both strings.

2) s1 = abc@c , s2 = cd@ee Modified s1 = abc, Modified s2 = dee If you notice above example ‘@’ and ‘c’ were common characters and both have been deleted from both strings.

Program:

public class commonCharacters {
    public static void main(String[] args) {
    String s1 = "abc@c";
    String s11 = s1;
    String s2 = "cd@ee";
    String s22 = s2;

    for (int i = 0; i <= s1.length() - 1; i++) {
        if (s2.contains((String.valueOf(s1.charAt(i))))) {
            s22 = s22.replaceFirst(String.valueOf(s1.charAt(i)), "");
        }   
    }
    System.out.println("removed common characters in string " + s2 + " is =" + s22);

    for (int i = 0; i <= s2.length() - 1; i++) {
        if (s1.contains((String.valueOf(s2.charAt(i))))) {
            s11 = s11.replaceFirst(String.valueOf(s2.charAt(i)), "");
        }
    }
    System.out.println("removed common characters in string " + s1 + " is =" + s11);
    System.out.println("After concat-Remove Common characters in two strings = " + s11 + s22);
    }
}

Output:

Remove common characters from given strings
