// Instantiating a Workbook object
Workbook workbook = new Workbook(dataDir + "book1.txt");

// Accessing the first worksheet in the TXT file
Worksheet worksheet = workbook.getWorksheets().get(0);

// Finding the cell containing the specified formula
Cells cells = worksheet.getCells();

// Instantiate FindOptions
FindOptions findOptions = new FindOptions();

// Finding the cell containing a string value that starts with Or
findOptions.setLookAtType(LookAtType.START_WITH);

Cell cell = cells.find("SH", null, findOptions);

// Printing the name of the cell found after searching 
System.out.println("Name of the cell containing String: " + cell.getName());
