Can someone tell me why

Question

Can someone tell me why is the ctrl not returned back to the println stmt of method counter after the method counterRecursion is executed???
pgm
class Trial1
     int ct=0;
     void counter(String word)
          counterRecursion(word);
          System.out.println(ct);
     void counterRecursion(String w)
          if (w!=null)
               switch (w.charAt(0))
                    case 'a':
                    case 'e':
                    case 'i':
                    case 'o':
                    case 'u': ct++;
                    default:counterRecursion(w.substring(1,w.length()));
class Trial2
     public static void main(String args[])
          try
               Trial1 c=new Trial1();
               c.counter("hello");
          catch(Exception e)
     }

What fsato4 means is never use an empty catch block:
try {
    // code
catch (Exception e) {}If there's an error anywhere (as it seems it's happening) it is being ignored.
Using:
try {
    // code
catch (Exception e) {
    // do something with the exception, don't simply ignore it
    e.printStackTrace();
}Prints any error in the console.
