Constructor Detail

Character

public Character(char value)

Method Detail

charValue

public char charValue()

Return the character this object represents.

Returns:

equals

public boolean equals(Object other)

Description copied from class: Object

Returns if this object is considered equal to the other object.

Overrides:

equals in class Object

Parameters:

other - Another object to compare to.

Returns:

true if this object is considered equal to the other object.

hashCode

public int hashCode()

Description copied from class: Object

Returns a hashCode for the object. The general contract of hashCode is:

An object must return the same hash code for its entire existence.

If two objects are considered equal by the equals() method, they should return the same hash code. Not all Objects will do this and you should only use hashCode() from Objects which declare an overrided version of hashCode(). The only Objects which provide consistent and correct hash codes under Ewe are Object, String and Class.

Overrides:

hashCode in class Object

isUpperCase

public static boolean isUpperCase(char ch)

isLowerCase

public static boolean isLowerCase(char ch)

isSpaceChar

public static boolean isSpaceChar(char ch)

isWhitespace

public static boolean isWhitespace(char ch)

isDigit

public static boolean isDigit(char ch)

isLetter

public static boolean isLetter(char ch)

isLetterOrDigit

public static boolean isLetterOrDigit(char ch)

isTitleCase

public static boolean isTitleCase(char ch)

toUpperCase

public static char toUpperCase(char ch)

toLowerCase

public static char toLowerCase(char ch)

toTitleCase

public static char toTitleCase(char ch)

toString

public String toString()

Converts the wrapped character into a String.

Overrides:

toString in class Object

Returns:

a String containing one character -- the wrapped character of this instance

toString

public static String toString(char ch)

Returns a String of length 1 representing the specified character.

Parameters:

ch - the character to convert

Returns:

a String containing the character
