Character class Methods in Java Part -II

 java.lang.Character

The Character class wraps a value of the primitive type char in an object. An object of class Character contains a single field whose type is char.

In addition, this class provides a large number of static methods for determining a character's category (lowercase letter, digit, etc.)and for converting characters from uppercase to lowercase and vice versa.


Some methods of Character class


hashCode()It returns a hash code for this Character (or the hash code value of the char value).


Character.highSurrogate()It returns the leading surrogate (a high surrogate code unit) of the surrogate pair representing the specified supplementary character (Unicode code point) in the UTF-16 encoding.


Character.isAlphabetic() It determines if the specified character (Unicode code point) is alphabetic.


Character.isBmpCodePoint()It determines whether the specified character (Unicode code point)is in the Basic Multilingual Plane (BMP).


Character.isDefined() It determines if a character (Unicode code point) is defined in Unicode. 


Character.isDigit()It determines if the specified character is a digit.


Character.isHighSurrogate() It determines if the given char value is a Unicode high-surrogate code unit.


Character.isIdentifierIgnorable()It determines if the specified character should be regarded as an ignorable character in a Java identifier or a Unicode identifier.


Character.isIdeographic() It determines if the specified character (Unicode code point) is a CJKV(Chinese, Japanese, Korean, and Vietnamese) ideograph, as defined by the Unicode Standard.


Character.isISOControl()It determines if the specified character is an ISO control character. 


Character.isJavaIdentifierPart() It determines if the specified character may be part of a Java identifier as other than the first character.


Character.isJavaIdentifierStart()It determines if the specified character is permissible as the first character in a Java identifier.


Character.isLetter()It determines if the specified character is a letter.


Character.isLetterOrDigit()It determines if the specified character is a letter or digit.


Character.isLowerCase()It determines if the specified character is a lowercase character.


Character.isLowSurrogate(): It determines if the given char value is a Unicode low-surrogate code unit(also known as a trailing-surrogate code unit).


Character.isMirrored()It determines whether the character is mirrored according to the Unicode specification. Mirrored characters should have their glyphs horizontally mirrored when displayed in text that is right-to-left.


Character.isSpaceChar()It determines if the specified character is a Unicode space character.


Character.isSupplementaryCodePoint()It determines whether the specified character (Unicode code point)is in the supplementary character range.


Character.isSurrogate() It determines if the given char value is a Unicode surrogate code unit.
