Taking a word as many chars to compare them in an ArrayList

Question

I have like a crossword. I gotta print the information and let the user insert the answer. But i have trouble comparing what the user gives me with the Arraylist i have. I don't know where the error is. Help pls

package mundo;

public class Letra {

// Atributos
private char caracter;

/**
* Construye una Letra <br>
* <b>post: </b> Se construye una letra con un caracter dado
* @param caracter - caracter representado por la Letra
*/
public Letra(char caracter){
this.caracter = caracter;
}

//métodos dar y cambiar
public char darCaracter() {
return caracter;
}

public void cambiarCaracter(char caracter) {
this.caracter = caracter;
}
public boolean esIgual(char c){
return caracter==c;
}
}

That is the first one.

package mundo;

public class Palabra {

// Atributos
private Letra[] letras;

/**
* Construye una palabra <br>
* <b>post: </b> Se construyó la palabra, inicializando el arreglo de letras
* y llenandolo, con los caracteres de la palabra
* @param palabra - Cadena con la palabra
*/
public Palabra(String palabra) {
letras = new Letra[palabra.length()];
char[] letricas = palabra.toCharArray();
for (int i = 0; i < letricas.length; i++) {
letras[i] = new Letra(letricas[i]);
}
}

// Método dar
public Letra[] darLetras() {
return letras;
}
/**
*
* @param p
* @return
*/

public boolean esIgual(Palabra p){

boolean iguales = letras.length==p.darLetras().length;

for (int i = 0; i < letras.length && iguales; i++) {

iguales &= letras[i].esIgual(p.darLetras()[i].darCaracter());

}

return iguales;
}
}

This is the second one.

package mundo;

import java.util.ArrayList;

public class Crucigrama {

//Constantes
public final static int FILASC = 10;
public final static int COLUMNASC = 23;

// Atributos
// Matriz de caracteres que componen el crucigrama
private Letra[][] caracteres;

// Lista de respuestas del crucigrama
private ArrayList<Palabra
