  - asList
```
public static java.util.List<java.lang.Integer> asList(int... backingArray)

    Parameters:
    
    backingArray - the array to back the list

  - tryParse
```
public static java.lang.Integer tryParse(java.lang.String string)
```
    Parses the specified string as a signed decimal integer value. The ASCII character '-' ('\u002D') is recognized as the minus sign.
    Unlike Integer.parseInt(String), this method returns null instead of throwing an exception if parsing fails. Additionally, this method only accepts ASCII digits, and returns null if non-ASCII digits are present in the string.
    Note that strings prefixed with ASCII '+' are rejected, even under JDK 7, despite the change to Integer.parseInt(String) for that version.
    
    Parameters:
    
    string - the string representation of an integer value
    
    Returns:
    
    the integer value represented by string, or null if string has a length of zero or cannot be parsed as an integer value
