I am writing a Java program using JBuilder 2, to create a Hashtable
containing a large number of entries, in which the values stored are strings
of random binary data 10 bytes long.  I am using:

BigInteger(int, Random)

to generate the random values for the binary strings, as standard integers
and longs are not large enough.

Is there a way to use put() to place these randomly generated binary strings
in the Hashtable?

e.g.

Object Key = "123456789";
BigInteger Value = new BigInteger(80,new Random(0));

put(Key,(Object)Value); // this gives a compilation error as below

Error: (33) method put(java.lang.Object, java.lang.Object) not found in
class table.

Any help and examples would be greatly appreciated,

Sarah.
