There aren't any "variable variables" (that is variables with variable names) in Java, but you can create Maps or Arrays to deal with your particular issue. When you encounter an issue that makes you think "I need my variables to change names dynamically" you should try and think "associative array". In Java, you get associative arrays using Maps.

That is, you can keep a List of your arrays, something like:

List kList = new ArrayList();
for(int k = 0; k < 5; k++){
   kList.add(new String[3]);
}

Or perhaps a little closer to what you're after, you can use a Map:

Map kMap = new HashMap();
for(int k = 0; k < 5; k++){
  kMap.put(k, new String[3]);
}
// access using kMap.get(0) etc..
