Compare two strings

[roud9]

Hello,

I wrote a little program that lets you compare the characters and display the number that are well or poorly placed, but I would like if there is a character in string1 that is not in string2, it is ignored. For example if string1: ABCD and string2 : ANBD, I want the program to tell me "2 well placed and 1 misplaced", N being ignored because it is not in the two chains. Here is what I have now:

public class Main
{
 
    static String chaine1 = "ABCD";
    static String chaine2 = "BACD";
    static int compteurBienPlaces;
    static int compteurMalPlaces;
 
    public static void main(String[] args)
    {
        for (int i = 0; i < chaine1.length(); i++)
        {
            char[] tableauChaine1 = chaine1.toCharArray();
            char[] tableauChaine2 = chaine2.toCharArray();
 
            if (tableauChaine1[i] == tableauChaine2[i])
            {
                System.out.println("Le caractère " + tableauChaine1[i] + " est"
                        + " bien placé");
                compteurBienPlaces++;
            }
            else if (tableauChaine1[i] != tableauChaine2[i])
            {
                System.out.println("Le caractère " + tableauChaine1[i] + " est"
                        + " mal placé");
                compteurMalPlaces++;
            }
        }
        System.out.println("Le nombre de caractères bien placés est de "
                + compteurBienPlaces + " et " + compteurMalPlaces + " sont mal "
                + "placés.");
    }
}

Thanks

I don't think you have to convert the Strings to character arrays. The String class has two neat methods you could use to solve your problem: charAt() and indexOf().

Hope this helps,
