```
    Convert a String to a long, returning a default value if the conversion fails.
    
    If the string is null, the default value is returned.
```
   NumberUtils.toLong(null, 1L) = 1L
   NumberUtils.toLong("", 1L)   = 1L
   NumberUtils.toLong("1", 0L)  = 1L
 
```
    Parameters:
    
    str - the string to convert, may be null
    
    defaultValue - the default value
    
    Returns:
    
    the long represented by the string, or the default if conversion fails
  - toInt
```
public static int toInt(String str,
                        int defaultValue)
```
    Convert a String to a int, returning a default value if the conversion fails.
    
    If the string is null, the default value is returned.
```
   NumberUtils.toInt(null, 1) = 1
   NumberUtils.toInt("", 1)   = 1
