Getting into Java: French Verb Conjugation Program

Reading from files is something I have not done a lot of, so I will have to look around a bit on how to do that. Before I start playing with that, however, I want to make sure the rest of my program is solid. (Or at least promoting good habits)

I went through my code and rewrote it to be more organized. I changed some names. I changed how the information is stored - instead of storying the conjugated verb in an array, I have a function return the conjugated form of the verb given a pronoun input. tense and infinitive are set as final variables that are defined during the object's creation. Imperfect verb endings are independent of the verb type, so I have the method check for type only if tense is present. If no tense is entered, the program defaults to present.

I think that's the basis of what I changed. I have been working on and off of this for the past few hours so my memory is a bit foggy. I tried to hit everything you guys mentioned, but I might have missed something.

 LesPommes.java

Code:

import java.util.Scanner;

public class LesPommes {
    
    public static void main( String args[]){
        StartUp();
        
        for(;;){
            Scanner input = new Scanner(System.in);
            String in = input.nextLine();                
            
            String infinitive = in.split(" ")[0];
    
            String tense = "present"; // If no tense is entered, default to present
            if (in.split(" ").length >= 2){
                tense = in.split(" ")[1];
            }
            
            Verb MyVerb = new Verb(infinitive, tense);
            
            for (int i = 0; i < 6; i++) {
                ;
            }
            for (int i = 0; i < 6; i++) {
                System.out.println(MyVerb.getPronoun(i) + " "
                        + MyVerb.conjugate(i));
            }
            System.out.println(""); //spacer after each verb to make the output more readable
            }
    }
    private static void StartUp(){
        /* Check if file "verbs.ini" exist
         * If false create it and fill with some sample verbs*/
        System.out.println("Program started. :D\n");        
    }
}

 Verb.java

Code:

public class Verb {
    
    private final String infinitive;
    private final String tense;

    //Verb Ending Arrays
    private static final String PRESENT_ER[] = { "e", "es", "e", "ons", "ez", "ent" };
    private static final String PRESENT_IR[] = { "is", "is", "it", "issons", "issez", "issent" };
    private static final String PRESENT_RE[] = { "s", "s", "", "ons", "ez", "ent" };
    
    private static final String IMPERFECT[] = { "ais", "ais", "ait", "ions", "iez", "aient" };
    //End of Verb Ending Arrays
    
    public static final String pronouns[] = { "Je", "Tu", "On", "Nous", "Vous", "Ils"};

    
    public Verb(String verbInfinitive, String verbTense){
        infinitive = verbInfinitive;
        tense = verbTense;
    }
    public String conjugate(int objPronounNo){
        /* Search the file for verbInfinitive,verbTense
         * If found, locate objPronoun and use objPronoun's verb form
         * If either search fails, default to regular conjugation
         */
        //default conjugation
        
        String verbEnding = infinitive.substring(infinitive.length()-2);
        String stem = infinitive.substring(0,infinitive.length()-2);
        
        if (tense.equals("present")){
            if (verbEnding.equals("er")) {
                
                return stem + PRESENT_ER[objPronounNo];
                
            } else if (verbEnding.equals("re")){
                
                return stem + PRESENT_RE[objPronounNo];
                
            } else if (verbEnding.equals("ir")){
                
                return stem + PRESENT_IR[objPronounNo];
                
            } else {
                return "Unknown verb ending: " + verbEnding;
            }
        } else if (tense.equals("imperfect")){
            
            return stem + IMPERFECT[objPronounNo];
            
        } else {
            return "Unknown verb tense: " + tense;
        }
    }
    public String getPronoun(int i){
        return pronouns[i];
    }
}

The current ini file I have laid out to use (but do not use yet):

 Spoiler

Code:

[etre,present]
je=suis
tu=es
on=est
nous=sommes
vous=etes
ils=sont

[etre,imperfect]
je=etais
tu=etais
on=etait
nous=etions
vous=etiez
ils=etaient

[avoir,present]
je=ai
tu=as
on=a
nous=avons
vous=avez
ils=ont

[aller,present]
je=vais
tu=vas
on=va

Aller is only irregular for the singular pronouns, in the present, so when the program tries to look up plural pronouns, it should return nothing and continue on with regular conjugation.

Adding accents where they belong is something I should do too.
