    public final class StringUtils
    extends java.lang.Object

Convenient class used only for uncapitalization Usually use commons lang but here we do not want to have such a dependency for only one feature

### Method Detail

#### uncapitalize

    public static java.lang.String uncapitalize(java.lang.String string)

#### getErrorMessage

    public static java.lang.String getErrorMessage(java.lang.Throwable t)

Returns the error message associated with the given Throwable. The error message returned will try to be as precise as possible, handling cases where e.getMessage() is not meaningful, like `NullPointerException` for instance.

Parameters:
  `t` - the throwable to get the error message from
Returns:
  the error message of the given exception

#### getStackTrace

    public static java.lang.String getStackTrace(java.lang.Throwable e)

Returns the exception stack trace as a String.

Parameters:
  `e` - the exception to get the stack trace from.
Returns:
  the exception stack trace

#### join

    public static java.lang.String join(java.lang.Object[] objs,
                        java.lang.String sep)

Joins the given object array in one string, each separated by the given separator. Example:

     join(new String[] {"one", "two", "three"}, ", ") -> "one, two, three"

Parameters:
  `objs` - The array of objects (`toString()` is used).
  `sep` - The separator to use.
Returns:
  The concatinated string.

#### encrypt

    public static final java.lang.String encrypt(java.lang.String str)

Encrypt the given string in a way which anybody having access to this method algorithm can easily decrypt. This is useful only to avoid clear string storage in a file for example, but shouldn't be considered as a real mean of security. This only works with simple characters (char < 256).

Parameters:
  `str` - the string to encrypt
Returns:
  the encrypted version of the string

#### decrypt

    public static final java.lang.String decrypt(java.lang.String str)

Decrypts a string encrypted with encrypt.

Parameters:
  `str` - the encrypted string to decrypt
Returns:
  The decrypted string.

#### repeat

    public static java.lang.String repeat(java.lang.String str,
                          int count)
