Handling Errors

y = cls.myprimes(1, new Double((double)n));

return (double[])((MWArray)y[0]).getData();

}

/* Catches the exception thrown by anyone */

catch (Exception e)

{

System.out.println("Exception: " + e.toString());

return new double[0];

}

finally

{

MWArray.disposeArray(y);

if (cls != null)

cls.dispose();

}

Code Fragment: Catching Multiple Exception Types

This second, and more general, variant of this example diffe rentiates between

an exce ption generated in a compiled method call and all other exception

types by introducing two

catch clauses as follows:

public double[] getprimes(int n)

{

myclass cls = null;

Object[] y = null;

try

{

cls = new myclass();

y = cls.myprimes(1, new Double((double)n));

return (double[])((MWArray)y[0]).getData();

}

/* Catches the exception thrown by myprimes */

catch (MWException e)

{
