Comparing characters in 2 char Array using Java

Question

I am a beginner in Java and I will like to know if there's a way to compare characters in a char Array with other characters in another char Array in order to see if they have characters that match. Not to see if they contain exactly the same characters in the same sequence as most examples explain.

For instance:

char [] word1= {'a','c','f','b','e'};

char[] word2= {'a','b','c','d','e','h','j','f','i','m'};

and using maybe if statements to say that word1 contains the characters in word2 so it is correct. Else it is incorrect if word2 is missing at least one character that word1 has.

Answer 1

I created a little snippet and think it is what you are looking for:

public class Main {

    public static void main(String[] args) {
        char[] word1= {'a','c','f','b','e'};
        char[] word2= {'a','b','c','d','e','h','j','f','i','m'};
    
        System.out.println(Contains(word1, word2));
    }

    private static boolean Contains(char[] arr1, char[] arr2) {
        for (int i = 0; i < arr1.length; i++) {
            boolean containsChar = false;
            for (int j = 0; j < arr2.length; j++) {
                if (arr1[i] == arr2[j]) containsChar = true;
            }
            if (!containsChar) return false; // arr2 does not contain arr1[i]
        }
        return true;
    }

}
