   static int[] x = new int[0];
   static {/*  w w  w.  j  a va  2  s . com*/
      x[0] = 10;
   }

   public static void main(String[] args) {
      Main ax = new Main();
   }
}

Select 1 option 

A. It will throw NullPointerException at runtime.
B. It will throw ArrayIndexOutOfBoundsException at runtime.
C. It will throw ExceptionInInitializerError at runtime.

Even though the line x [0] = 10; will throw java.lang.ArrayIndexOutOfBoundsException,

JVM will wrap it and rethrow java.lang.ExceptionInInitializerError.
