hey, i saw
that reply is for ice not for u
sorry
please provide a syntax for converting string to biginteger, i did't understand that.
please help me.........

Each hexadecimal digit represents four binary digits (bits) (also called nibble), and the first use of hexadecimal notation is a representation of the binary values encoded nice man on the computer and digital electronics.

sorry sir,
please post the program if u can,
or atlest post syntax...
any way, thanks sir that is very useful link but i am very new to java so i cant understand.. please help me

//BigInteger(String val)
//Translates the decimal String representation of a BigInteger into a BigInteger.
BigInteger bi1 = new BigInteger("123123414123412341241243");

If you look at that link you will find the methods that do what you want. Create 2 BigInteger objects and then call the methods you want:

BigInteger bi1 = new BigInteger("123123414123412341241243");
bi1.method(<argumnets>);
