Re: Exception in thread "main" java.util.zip.ZipException: Not in GZIP format

Good Morning,

I'm trying in my program to Compress/Decompress data using GZIP streams and when using the charset "ISO-8859-1", everything working well but when changing the charset to "UTF-8", i'm getting the Error message "Exception in thread "main" java.util.zip.ZipException: Not in GZIP format".
this is my code:

public static String compress(String str) throws IOException {
            if (str == null || str.length() == 0) {
                return str;
            }
            System.out.println("String length : " + str.length());
            ByteArrayOutputStream out = new ByteArrayOutputStream();
            GZIPOutputStream gzip = new GZIPOutputStream(out);
            gzip.write(str.getBytes());
            gzip.close();
            String outStr = out.toString("UTF-8");
