RFR [8042990] Optimize conversion to hex string (original) (raw)

Hello!

There is a method Integer.toHexString(int), which produce a string with no extra leading zeroes. I found a couple of places in jdk, where it would be useful to have a variant of the method which pads the result with the required amount of zeroes.

Would you please take at the webrev? http://cr.openjdk.java.net/~igerasim/8042990/0/webrev/

It includes implementations of Integer.toHexString(int, int) and Long.toHexString(long, int) with the second argument standing for the minimum width of the produced string. It also contains a few replacements of the same behaving code with calls to these new methods.

Sincerely yours, Ivan
