- Method Detail
  - toLowerCase
```
public static char toLowerCase(char c)
```
    Convert the input to lowercase.
    This method does not honor the JVM locale, but instead always behaves as though it is in the US-ASCII locale. Only characters in the range 'A' through 'Z' are converted. All other characters are left as-is, even if they otherwise would have a lowercase character equivalent.
    
    Parameters:
    
    c - the input character.
    
    Returns:
    
    lowercase version of the input.
  - toLowerCase
```
public static String toLowerCase(String in)
```
    Convert the input string to lower case, according to the "C" locale.
    This method does not honor the JVM locale, but instead always behaves as though it is in the US-ASCII locale. Only characters in the range 'A' through 'Z' are converted, all other characters are left as-is, even if they otherwise would have a lowercase character equivalent.
    
    Parameters:
    
    in - the input string. Must not be null.
    
    Returns:
    
    a copy of the input string, after converting characters in the range 'A'..'Z' to 'a'..'z'.
  - capitalize
```
public static String capitalize(String str)
```
    Borrowed from commons-lang StringUtils.capitalize() method.
    Capitalizes a String changing the first letter to title case as per Character.toTitleCase(char). No other letters are changed.
    A null input String returns null.
    
    Parameters:
    
    str - the String to capitalize, may be null
    
    Returns:
    
    the capitalized String, null if null String input

  - equalsIgnoreCase
```
public static boolean equalsIgnoreCase(String a,
                                       String b)
```
    Test if two strings are equal, ignoring case.
    This method does not honor the JVM locale, but instead always behaves as though it is in the US-ASCII locale.
    
    Parameters:
    
    a - first string to compare.
    
    b - second string to compare.
    
    Returns:
    
    true if a equals b
  - compareIgnoreCase
```
public static int compareIgnoreCase(String a,
                                    String b)
```
    Compare two strings, ignoring case.
    This method does not honor the JVM locale, but instead always behaves as though it is in the US-ASCII locale.
    
    Parameters:
    
    a - first string to compare.
    
    b - second string to compare.
    
    Returns:
    
    negative, zero or positive if a sorts before, is equal to, or sorts after b.
    
    Since:
    
    2.0
  - compareWithCase
```
public static int compareWithCase(String a,
                                  String b)
```
    Compare two strings, honoring case.
    This method does not honor the JVM locale, but instead always behaves as though it is in the US-ASCII locale.
    
    Parameters:
    
    a - first string to compare.
    
    b - second string to compare.
    
    Returns:
    
    negative, zero or positive if a sorts before, is equal to, or sorts after b.

  - toBoolean
```
public static boolean toBoolean(String stringValue)
```
    Parse a string as a standard Git boolean value. See toBooleanOrNull(String).
    
    Parameters:
    
    stringValue - the string to parse.
    
    Returns:
    
    the boolean interpretation of value.

    IllegalArgumentException - if value is not recognized as one of the standard boolean names.
  - toBooleanOrNull
```
public static Boolean toBooleanOrNull(String stringValue)
```
    Parse a string as a standard Git boolean value.
    The terms yes, true, 1, on can all be used to mean true.
    The terms no, false, 0, off can all be used to mean false.
    Comparisons ignore case, via equalsIgnoreCase(String, String).
    
    Parameters:
    
    stringValue - the string to parse.
    
    Returns:
    
    the boolean interpretation of value or null in case the string does not represent a boolean value
  - join

    Parameters:
    
    parts - Strings to join
    
    separator - separator used to join all but the two last elements
    
    lastSeparator - separator to use for joining the last two elements
    
    Returns:
    
    a String with all the joined parts
  - isEmptyOrNull
```
public static boolean isEmptyOrNull(String stringValue)
```
    Test if a string is empty or null.
