Class Overview
Utility methods for safe conversions of strings or boxed representations of numbers, to numbers. Base 10, 16 and 8 are supported. Numbers in bases 16 and 8 require explicit prefix or suffix. Otherwise, it is assumed that the string represents a number in base 10. The exceptions are:
- Strings starting with "0x" or ending with "h": assume base 16
- Strings starting with "0?" (? denoting any character): assume base 8

Public Methods
public static int getHexPossibility (String s)
Determine if a string may, must, or cannot be representing a hexadecimal number.
Returns
- 0=cannot, 1=may, 2=must (be a hex number)
public static int stringToInt (String s, int def, int defaultBase)
Convert to int.
Parameters
| s | input string |
|---|---|
| def | the default value |
Returns
- the converted value or the default value on error
public static int stringToInt (String s, int def)
Convert to int. The default conversion base, if undetermined, will be 10.
Parameters
| s | input string |
|---|---|
| def | value to be returned on error |
Returns
- the converted value
public static int stringToInt (String s)
Convert to int. The default conversion base, if undetermined, will be 10.
Parameters
| s | input string |
|---|
Returns
- the converted value, 0 on error
public static Integer stringToIntUnsafe (String s)
Throws
| NumberFormatException |
|---|
public static long stringToLong (String s, long def)
Convert to long. The default conversion base, if undetermined, will be 10.
Parameters
| s | input string |
|---|---|
| def | value to be returned on error |
Returns
- the converted value
public static long stringToLong (String s)
Convert to long. The default conversion base, if undetermined, will be 10.
Parameters
| s | input string |
|---|
Returns
- the converted value, 0 on error
public static long stringToLong (String s, long def, int defaultBase)
Convert to long.
Parameters
| s | the input string |
|---|---|
| def | the default value if the conversion failed |
| defaultBase | the default base if the base representation could not be determined |
Returns
- the converted value or the default value on error
public static Long stringToLongUnsafe (String s)
public static int toInt (Object o)
Best effort conversion of an object to an integer. If the conversion fails, the value returned is 0.
Parameters
| o | a String or an Integer |
|---|
Returns
- the converted int
public static int toInt (Object o, int def)
Best effort conversion of an object to an integer.
Parameters
| o | a String or an Integer |
|---|---|
| def | default value to return if the conversion fails |
Returns
- the converted int
public static long toLong (Object o)
Best effort conversion of an object to an integer. If the conversion fails, the value returned is 0.
Parameters
| o | a String or an Long |
|---|
Returns
- the converted long
public static long toLong (Object o, long def)
Best effort conversion of an object to a long.
Parameters
| o | a String or an Long |
|---|---|
| def | default value to return if the conversion fails |
Returns
- the converted long
