Проблема с if else и классом

vovlo

public class vovlo {
 public void setTextfromFolder(String ff){
         File fileFOL = new File(ff);
  try {
        Scanner s = new Scanner(fileFOL).useDelimiter("\n+");
        while (s.hasNext()) {
            if (s.hasNextInt()) {
                textArea.appendText(s.nextInt() + "\n "); } else {
                textArea.appendText(s.next() + " "+"\n"); 
            }}
    } catch (FileNotFoundException ex) {

    }

Почему January работает, а остальные месяца нет?

     if(DAY.equals(Textday.getText()) & MonChoose.getValue().toString().equals("January")){
              vovlo koko = new vovlo();
              koko.setTextfromFolder("./src/yourDATA/2017/JANUARY/"+Textday.getText()+" JANUARY.txt");}
else if(DAY.equals(Textday.getText())&MonChoose.getValue().toString().equals("February")){
              vovlo hoho = new vovlo();
              hoho.setTextfromFolder("./src/yourDATA/2017/FEBRUARY/"+Textday.getText().toString()+"FEBRUARY.txt");}
else if(DAY.equals(Textday.getText()) & MonChoose.getValue().toString().equals("March")){
              vovlo koko = new vovlo();
              koko.setTextfromFolder("./src/yourDATA/2017/MARCH/"+Textday.getText()+" MARCH.txt");}
else if(DAY.equals(Textday.getText()) & MonChoose.getValue().toString().equals("April")){
              vovlo koko = new vovlo();
              koko.setTextfromFolder("./src/yourDATA/2017/APRIL/"+Textday.getText()+" APRIL.txt");}
