Converting ASCII text (byte array ending in null) to a String

Question

Hi all,
I am trying to convert a null terminated ascii string stored in a byte array to a java String. When I pass the byte array to the String constructor it
does not detect/interpret the null as a terminator for the ascii string. Is this something I have to manually program in? ie Check for where the null is and then
pass that subarray of everything before the null to the String constructor?
example of problem
//               A   B  C   D   null   F   (note F is junk in the array, and should be ignored since it is after null)
byte[] asciiArray = { 65, 66, 67, 68, 0,  70 };
System.out.println(new String(asciiArray, "UTF-8"));
//this prints ABCD"sqare icon"F

Why do you expect the null character to terminate the string? If you come from a C or C++ background, you need to understand that java.lang.String is not just a mere character array. It's a full-fledged Java object that knows its length without having any need for null terminator. So Ascii 0 is just another character for String object. To achieve what you want to do, you have to manually loop through the byte array and stop when you encounter a null character.
