What will be the output of the following Java code?

class exception_handling 
{
    public static void main(String args[])
    {
        try 
        {
            throw new NullPointerException ("Hello");
            System.out.print("A");
        }
        catch(ArithmeticException e) 
        {
      System.out.print("B");        	
        }
    }
}
