Java. String cannot be converted to Object[]

Question

how can I resolve the issue? I am reading the data from Excel file and the output is in String.
The method "getData" with DataProvider requires Object[][] return type.

public class Utilities extends Page {

    @DataProvider(name = "readProductNumber")
    public Object[] getData(Method method) {

        ReadDataFromExcel readDataFromExcel = new ReadDataFromExcel();
        String data = readDataFromExcel.ReadCellData(1, 0);


        return data;

    }
}

Error:(17, 16) java: incompatible types: java.lang.String cannot be converted to java.lang.Object[]

String is an Object, but your method needs to return an Object array.

You could put it into an array like so: return new Object[]{data}
