Constructor Detail

• Character

  public Character(char value)

  Constructs a new Character with the specified primitive char value.

  Parameters:

  value - the primitive char value to store in the new instance.

Method Detail

• charValue

  public char charValue()

  Gets the primitive value of this character.

  Returns:

  this object's primitive value.

• valueOf

  public static Character valueOf(char c)

  Returns a Character instance for the char value passed. For ASCII/Latin-1 characters (and generally all characters with a Unicode value up to 512), this method should be used instead of the constructor, as it maintains a cache of corresponding Character instances.

  Parameters:

  c - the char value for which to get a Character instance.

  Returns:

  the Character instance for c.

  Since:

  1.5

• equals

  public boolean equals(Object object)

  Compares this object with the specified object and indicates if they are equal. In order to be equal, object must be an instance of Character and have the same char value as this object.

  Overrides:

  equals in class Object

  Parameters:

  object - the object to compare this double with.

  Returns:

  true if the specified object is equal to this Character; false otherwise.

  See Also:

  Object.hashCode()

• hashCode

  public int hashCode()

  Returns an integer hash code for this character.

  Overrides:

  hashCode in class Object

  Returns:

  this object's hash code.

  See Also:

  Object.equals(java.lang.Object)

• toString

  public String toString()

  Converts this character to its string representation.

  Overrides:

  toString in class Object

  Returns:

  the character converted to a string.

• digit

  public static int digit(char c,
          int radix)

  Convenience method to determine the value of the specified character c in the supplied radix. The value of radix must be between MIN_RADIX and MAX_RADIX.

  Parameters:

  c - the character to determine the value of.

  radix - the radix.

  Returns:

  the value of c in radix if radix lies between MIN_RADIX and MAX_RADIX; -1 otherwise.

• isDigit

  public static boolean isDigit(char c)

  Indicates whether the specified character is a digit.

  Parameters:

  c - the character to check.

  Returns:

  true if c is a digit; false otherwise.

• isLowerCase

  public static boolean isLowerCase(char c)

  Indicates whether the specified character is a lower case letter.

  Parameters:

  c - the character to check.

  Returns:

  true if c is a lower case letter; false otherwise.

• isUpperCase

  public static boolean isUpperCase(char c)

  Indicates whether the specified character is an upper case letter.

  Parameters:

  c - the character to check.

  Returns:

  true if c is a upper case letter; false otherwise.

• toLowerCase

  public static char toLowerCase(char c)

  Returns the lower case equivalent for the specified character if the character is an upper case letter. Otherwise, the specified character is returned unchanged.

  Parameters:

  c - the character

  Returns:

  if c is an upper case character then its lower case counterpart, otherwise just c.

• toUpperCase

  public static char toUpperCase(char c)

  Returns the upper case equivalent for the specified character if the character is a lower case letter. Otherwise, the specified character is returned unchanged.

  Parameters:

  c - the character to convert.

  Returns:

  if c is a lower case character then its upper case counterpart, otherwise just c.
