MemPOI - The most basic example returning byte[]

MemPOIBasicByteArray.java

try {

  // creates MemPOI using its builder
  MemPOI memPOI = MempoiBuilder.aMemPOI()
    .addMempoiSheet(new MempoiSheet(prepStmt))
    .build();
            
  // exports to byte array
  CompletableFuture<byte[]> fut = memPOI.prepareMempoiReportToByteArray();
  
  // gets the generated report byte array
  byte[] bytes = fut.get();
            
} catch (Exception e) {
   e.printStackTrace();
