Here's the code snippet:

```
public static void main (String[]arg) 
{
    char ca = 'a' ; 
    char cb = 'b' ; 
    System.out.println (ca + cb) ; 
}

```

The output is: 

```
195

```

Why is this the case? I would think that `'a' + 'b'` would be either `"ab"` , `"12"` , or `3`.

Whats going on here?
