Array variable “might not have been initialized”

Question

I get the error:

TestCounter.java:115: variable counters might not have been initialized counters[i] = new Counter(i);

Answer 1

You need to initialize the counters array. Something like this:

if(success) 
  {  
   Counter[] counters=new Counters[30];

   for(int i=0; i<30; i++)
   {
       counters[i] = new Counter(i);
       System.out.println(counters[i].whatIsCounter());
   }
  }

By stating Counter[] counters you are not actually creating an array, you are simple declaring a reference variable counters of type Counter[].

Counter[] counters=new Counters[30] will create an array of type Counter of size 30 with each element holding null reference.

Answer 2

You haven't created the array, you've just declared the variable.

You need to do this:

Counter[] counters = new Counter[30];

or something similar
