Method Detail

capitalize

public static String capitalize(String string)

Returns a capitalized version of the given string. If the given string already starts with an uppercase character, the original string is returned. Otherwise, the string with the first letter uppercased is returned.

Parameters:

string - the string

Returns:

the capitalized string

split

public static String[] split(String string,
             char separatorChar)

Calls return split(string, separatorChar, '\\').

Parameters:

string - the string

separatorChar - the separator character

Returns:

the string arrays

split

public static String[] split(String string,
             char separatorChar,
             char escapeChar)

Splits the given string at the given separator character. The separator character can be escaped by preceding it with the given escape character. Doubling the escape character results in the escape character. Escaping any other character results in that character.

Parameters:

string - the string to split

separatorChar - the separator character

escapeChar - the escape character

Returns:

the string array

getLongHashCode

public static long getLongHashCode(String string)

Version of the usual String.hashCode() method that computes a long hash code instead of an int hash code, using the same algorithm as the original method. Using a rough estimation, the String.hashCode() method wraps around after roughly 7 characters, whereas this method wraps around after roughly 13 characters.

Parameters:

string - the string

Returns:

the long hash code

isEmpty

public static boolean isEmpty(String string)

Checks if the given string is null or empty.

Parameters:

string - the string

Returns:

true or false

isNotEmpty

public static boolean isNotEmpty(String string)

Checks if the given string is non-null and not empty.

Parameters:

string - the string

Returns:

true or false
