Time for action – examining the output data with Java

To show that the data is accessible from multiple languages, let's also display the job output using Java.

1. Create the following as OutputRead.java:

   import java.io.File;
   import java.io.IOException;
   
   import org.apache.avro.file.DataFileReader;
   import org.apache.avro.generic.GenericData;
   import org.apache.avro. generic.GenericDatumReader;
   import org.apache.avro.generic.GenericRecord;
   import org.apache.avro.io.DatumReader;
   
   public class OutputRead
   {
       public static void main(String[] args) throws IOException
       {
           String filename = args[0] ;
   
           File file=new File(filename) ;
   DatumReader<GenericRecord> reader= new 
   GenericDatumReader<GenericRecord>();
   DataFileReader<GenericRecord>dataFileReader=new 
   DataFileReader<GenericRecord>(file,reader);
   
           while (dataFileReader.hasNext())
           {
   GenericRecord result=dataFileReader.next();
               String output = String.format("%s %d",
   result.get("shape...
