Convert Hex to Decimal and Decimal to TimeStamp in JAVA

Question

I have facing Problem in Parsing 16 digit hex string to decimal integer value.

I have tried following code for converting hex to decimal:

    String HexString= "0000113fc208dff"; 
    int dec= Long.parseLong(HexString);

But its throwing NumberFormatException: Invalid int ...

Now How do i Convert to Decimal/Binary and Further Convert Decimal/Binary to Time Stamp ??

Any help would be appreciated.

It's still an `int` (or in this case, `long`). Try parsing it as a `long` and see what you turn up with. — Makoto, Jan 14 '15 at 07:12

The first parameter is the String, second parameter is the radix

long epoch=Long.parseLong(str, 16);

Then convert to Timestamp through Calendar

Calendar c=Calendar.getInstance();
c.setTimeInMillis(epoch);
