what this snippet will do?
hello,
im new to this, please help on this example what will be the output?
byte[] arrayOfByte = { (byte) 0xe7, (byte) 0x0a, (byte) 0x3f, (byte) 0x16, (byte) 0xcc, (byte) 0x16, (byte) 0x0c, (byte) 0xaf, (byte) 0x3d, (byte) 0x00, (byte) 0xd3, (byte) 0x0b, (byte) 0x71, (byte) 0x93, (byte) 0xc8, (byte) 0xf7};
int j = 0;
String str = "";
while (true)
{
if (j >= arrayOfByte.length)
return str;
str = str + Integer.toString(256 + (0xFF & arrayOfByte[j]), 16).substring(1); -can somebody explain what math happens here?
j++;
}
what will be in the str in the end?
many thanks
Re: what this snippet will do?
my advice is to simply use System.out.println(str); and find out.
as for the math itself, i will leave it to someone who knows. :)

Then you'll want to check this out when you are able to compile and run this yourself. This site is not supposed to be used as a substitute for your Java compiler and JVM.
