Hi All
I have a doubt in string functions

what is the difference between the following two lines of code???

String s = "hex = "+ Long.toString(254,16); // s = "hex = fe"

String s3 = Integer.toHexString(254);

The methods used in the above two statements are different but then wat is the difference between these two methods???

Thanks in advance

In terms of usage there is no difference between toString(254, 16) and toHexString(254), just as there is no difference between toString(254, 10) and toString(254), between toString(254, 8) and toOctalString(254) and between toString(254, 2) and toBinaryString(254). There is a difference in implementation which may cause one or the other to be slightly faster, but the difference won't be noticeable unless you call the method millions (billions) of times.
