Question

I need to delete a character from a character array and re-size the array. Until now, I have worked on replacing a particular character with a special character.

In this code I am searching for any matches that are found i.e , if any characters are matching in the male and female character array and if found I am replacing it with “*”. Instead of that I have to delete that character and resize the array.

private static void Compare(String Male,String Female) {

    char[] male;
    char[] female;
    // converting a string into charecter array

    male=Male.toCharArray();
    female=Female.toCharArray();

    //finding any matches i.e, any charecter is matching or not 
    for(int i=0;i<male.length;i++){

        for(int j=0;j<female.length;j++)
        {
            String m = Character.toString(male[i]);
            String fm = Character.toString(female[j]);
            if(m.equals(fm)){
            //if the charecters are equal  then  replacing them with "*"    

                male[i]='*';
                female[j]='*';

            }
        }
    }

Try this:

    String male = "maleg*$m-z";
    String female= "femal^\\$e-is";
    String deletedMale = male.replaceAll("["+Pattern.quote(female)+"]", "");
    String deletedFemale = female.replaceAll("["+Pattern.quote(male)+"]", "");
    System.out.println(deletedMale);
    System.out.println(deletedFemale);
