Alternative to deprecated getCellType

You can use:

cell.getCellTypeEnum()

Further to compare the cell type, you have to use CellType as follows:-

if(cell.getCellTypeEnum() == CellType.STRING){
      .
      .
      .
}

You can Refer to the documentation. Its pretty helpful:-

https://poi.apache.org/apidocs/org/apache/poi/ss/usermodel/Cell.html

    FileInputStream fis = new FileInputStream(new File("C:/Test.xlsx"));

    //create workbook instance
    XSSFWorkbook wb = new XSSFWorkbook(fis);

    //create a sheet object to retrieve the sheet
    XSSFSheet sheet = wb.getSheetAt(0);

    //to evaluate cell type
    FormulaEvaluator formulaEvaluator = wb.getCreationHelper().createFormulaEvaluator();

    for(Row row : sheet)
    {
        for(Cell cell : row)
        {
            switch(formulaEvaluator.evaluateInCell(cell).getCellTypeEnum())
            {
            case NUMERIC:
                System.out.print(cell.getNumericCellValue() + "\t");
                break;
            case STRING:
                System.out.print(cell.getStringCellValue() + "\t");
                break;
            default:
                break;

            }
        }
        System.out.println();
    }

This code will work fine. Use getCellTypeEnum() and to compare use just NUMERIC or STRING.

Use getCellType()

switch (cell.getCellType()) {
   case BOOLEAN :
                 //To-do
                 break;
   case NUMERIC:
                 //To-do
                 break;
   case STRING:
                 //To-do
                 break;
}

The accepted answer shows the reason for the deprecation but misses to name the alternative:

CellType    getCellTypeEnum()

where the CellType is the enum decribing the type of the cell.

The plan is to rename getCellTypeEnum() back to getCellType() in POI 4.0.
