How to compare these 2 arrays inside this while?

I am developing a game similar to Hangman, where the user has to hit the word chosen by the computer in up to 8 attempts.

The variable mascara is an array of characters that corresponds to the word the user sees on the screen (which may not display all letters) and the variable palavraSeparada is a character array that matches the word the user should guess

I’m in doubt in the loop while below. How do I check if the content of the two arrays is equal?

while(acertou==false&&errou<8){

    for(int i=0;i<mascara.length;i++){
        System.out.print(mascara[i]);
    }

    System.out.println("");
    letraDigitada = input.nextLine().charAt(0);

    for (int i=0;i<palavraSeparada.length;i++){
        if (letraDigitada == palavraSeparada[i]){
            mascara[i]=letraDigitada;
        }
    }
}
java

  • This is to implement a game of Mastermind (AKA Password)? What is the content of palavraSeparada? What is the expected content of mascara?

First, instead of acertou==false, use !acertou.

Second, use the method equals(char[], char[]) class java.util.Arrays.

Your code should look like this:

while (!acertou && errou < 8) {

    for (int i = 0; i < mascara.length; i++) {
        System.out.print(mascara[i]);
    }

    System.out.println("");
    letraDigitada = input.nextLine().charAt(0);

    for (int i = 0; i < palavraSeparada.length; i++) {
        if (letraDigitada == palavraSeparada[i]) {
            mascara[i] = letraDigitada;
        }
    }

    if (Arrays.equals(mascara, palavraSeparada)) acertou = true;
}

In the code, we still need to increase the errou in case the if that’s inside the for don’t enter once. I leave it to you to solve, but it’s easy. :)
