Fill a char array with a string without posting spaces

My goal is to create a program that counts hits by entering this keyboard, the problem is that I can not account for those that are beyond the first space, here I leave what I wrote:

public class CuentaCaracteres {

    static void toma(String cadena){
        System.out.print(cadena);
    }

    static String lectura(){
        String palabra;
        Scanner leer=new Scanner(System.in);
        return palabra=leer.next();
    }

    static char lecturaC(){
        char buscar;
        Scanner leer=new Scanner(System.in);
        return buscar=leer.next().charAt(0);
    }

    public static void main(String[] args) {
        String palabra="";
        char buscar='b';
        int coincidencia=0;

        System.out.println("Dime una palabra, te contabilizare el numero de coincidencias");
        palabra=lectura();

        char[]caracteres= palabra.replaceAll("\W ","" ).toCharArray();   

        System.out.println("elemento a buscar");
        buscar=lecturaC();
        for(int i=0; i<caracteres.length;i++){
            if(caracteres[i]==buscar) coincidencia++;
                System.out.println(caracteres[i]);
            }
            System.out.println("Hay " + coincidencia + " coincidencias en el vector");
        }    
}
