Arrayindex [resolved]

[Dillinger4]

Does anyone know why this would happen?
When the first loop is excuted i get an ArrayIndexOutOfBounds
exception. But the second loopruns fine.

public class Test{
        public static void main(String[] args){
           
         String s = new String("ABC"); 
         char[] c = new char[s.length()];         
         int[] intArray = new int[25]; 
       
         for(int i = 0; i < s.length(); i++){
              c[s.charAt(i)]++; // array index out of bounds
         }
      
        for(int k = 0 ;k < s.length(); ++k){
          c[s.charAt(k)]++; // runs fine 
        }
  }
}
