Cursor going out of bound

I have a scenerio in which i have to move the cursor to next and previous. I am runing into exception when the cursor is already at the first or last location, then it throws out of bound exception.

How to tackle this situation ? What is the best way to handle it and currently i am handling it with exception [try and catch].

 public boolean nextWord()
   {
 boolean isVald = false;
 try
 {
    i开发者_运维问答sVald = currentCursor.moveToNext();
    fillCurrentWord();

 } catch (Exception e)
 {
    Log.e("nextWord", e.toString());
 }

 return isVald;
  }

if (!currentCursor.isLast()){
    currentCursor.moveToNext();
    // ...
}

You can verify your current position using one of the following methods: isFirst(), isBeforeFirst(), isLast() or isAfterLast()
