MemPOIBasicFileName.java

  // creates destination file
  File file = new File("test.xlsx");

  // creates MemPOI using its builder
  MemPOI memPOI = MempoiBuilder.aMemPOI()
    .withFile(file)
    .addMempoiSheet(new MempoiSheet(prepStmt))
    .build();

  // exports to file
  CompletableFuture<String> fut = memPOI.prepareMempoiReportToFile();
  // gets the generated report absolute filename 
  String absoluteFileName = fut.get();

} catch (Exception e) {
    throw new MempoiRuntimeException(e);
