Ex 20: Create an exception class, which throws an exception if operand is nonnumeric in calculating modules. (Use command line arguments).

class NonNum extends Exception
{
NonNum()
{ super("the value is non numeric \n"); }
}
class s06_03
{
public static void main(String ar[])
{
int a,b,c=0;
try
{
a=Integer.parseInt(ar[0]);
throw new NonNum();
}
catch(NumberFormatException e)
{System.out.println(e);}
catch(NonNum e)
{ System.out.println(e);}
}
}
