Question: I need to display in excel a matrix, but my last column display special caracteres in excel.
I want to convert this last column in number or String, to be display correctly.

My matrix

```
data 
   = 'A1' [48]
     'A2' [44]
     'A3' [45]
     'A4' [46]

```

This last column (with brackets) seems to be double.

I want something as this :

```
data 
   = 'A1' 48
     'A2' 44
     'A3' 45
     'A4' 46

```

Answer: 
Try like this:

```
Class<String[]> cls = String[].class;

```
`String[].class` should do for you.
