{code:title=test.java|borderStyle=solid}
    public static long getUnzippedFileSize(byte[] zippedData){
        long byteSize = 0;
        try(ZipArchiveInputStream zipArchiveInputStream = new ZipArchiveInputStream(new ByteArrayInputStream(zippedData))){
            ArchiveEntry zipEntry = zipArchiveInputStream.getNextEntry();
            while(zipEntry != null){
                byteSize = byteSize + zipEntry.getSize();
                zipEntry = zipArchiveInputStream.getNextEntry();
