help with translation function

[kiltman]

hello,

im currently coding a function to translate between languages,

however im having some problems, heres what i have so far

public String translateEngAndFreToSol(int option) //option = 0 for english, 1 for french
    {
        String[] data = loadSave.getLoadedData().split("\\s"); // creates array of words (by splitting string where theres a space)
        String output = "";
        String word = "";
        
        for(int i = 0; i < data.length; i++)
        {
            String prev = data[i]; //used to store data incase current word is not in mini dictionary

            try
            {
                switch(option)
                {
                    case 0: word = dictionary.getEntryByEngWord(data[i]).getSolWord();
                            break;
                    case 1: word = dictionary.getEntryByFreWord(data[i]).getSolWord();
                            break;
                }
                output += word + " ";  
            }
            catch(NullPointerException e)  //if word is not stored in the dictionary then use the value thats currently there, probally not best way to handle this
            {
                output += prev + " ";
            }   
        }
        return output.trim();
    }

Hello, how are you?
