I am coding a program that reads a simple text file, reformats it and then
inserts it into a database.  Shown below is a code fragment from the
program:

try {
          while (ZipCodeFile.read(StateAbbrv) != -1) {
            String s = new String(StateAbbrv,0);
            ZipCodeFile.read();
            ZipCodeFile.read(ZipCodeRangeLow);
            ZipStringLow = new String(ZipCodeRangeLow,0);
            Low = Low.decode(ZipStringLow);
            ZipCodeLow = Low.intValue() * 100;
....


I have two questions.  First, the documentation says that the String
constructor I am using is "deprecated" and will not be supported in future
releases.  How can I recode this line to convert a byte array into a string?
Second, will I run into any problems allocating a new String variable every
time the loop encounters this line?
