Question

My return false statement doesn’t work as expected. I have a recursive method called “prosegui”, it works with most of the words i want to work with, but with a few of them the return false doesn’t return the value “false” as it should but continue and end up returning true.

if (contChar < this.parola.length() - 1) {
    if (this.parola.charAt(contChar+1)==matrice[i][j])
    {
        prosegui(proseguiI,proseguiJ,i,j,contChar+1);
    } 
    else 
    {
        System.out.println("FALSE");
        return false;
    }
}

System.out.println("TRUE");
return true;

I really don’t know how to sort it out.

EDIT:

the program print both “FALSE” and then “TRUE”

EDIT:

public boolean prosegui(int i, int j, int proseguiI, int proseguiJ, int contChar)
{
    if (contChar < this.parola.length() - 1)
    {
        int direzioneI=proseguiI-i;
        int direzioneJ=proseguiJ-j; 
        i=proseguiI+direzioneI;
        j=proseguiJ+direzioneJ;

        int cont;
        StringTokenizer st = new StringTokenizer(this.results);

        cont=0;

        char[][] matrice = new char[this.lung][this.lung];

        while (st.hasMoreTokens())
        {
             matrice[cont]=st.nextElement().toString().toCharArray();
             cont++;
        }

        if(this.parola.charAt(contChar+1)==matrice[i][j]){

        prosegui(proseguiI,proseguiJ,i,j,contChar+1);
    }
    else 
    {
        System.out.println("FALSE");
        return false;
    }
}

System.out.println("TRUE");
return true;
}

If this code is in the prosegui method, then when it calls itself here:

prosegui(proseguiI,proseguiJ,i,j,contChar+1);

The true/false returned by this call is never used.
