- forName() : java.lang.Character.UnicodeBlock.forName() returns the name of Unicode Blocks, which are determined by the Unicode Standards.
The method accepts argument as Canonical Block as per Unicode Standards.

public static final Character.UnicodeBlock forName(String block)
Parameters :
block : Name of UniCode Block.
Return :
instance of UniCode Block.
Exception :
-> IllegalArgumentException
-> NullPointerException
- of(char ch) : java.lang.Character.Subset.of(char ch) returns the UniCode Block having the argumented character or null if the character is not a part of any defined Unicode Block.
Syntax :
public static Character.UnicodeBlock of(char ch)
Parameters :
ch : character to be found.
Return :
returns the UniCode Block or null.
Exception :
-> IllegalArgumentException
- of(int UCPoint) : java.lang.Character.Subset.of(int UCPoint)returns the object having the argumented UniCode – Point or null if the character is not a part of any defined Unicode Block.
Syntax :
public final String toString()
Parameters :

public static void main(String[] args)
{
System.out.println( "Using UnicodeBlock.forName() : " );
System.out.println(Character.UnicodeBlock.forName( "OLDITALIC" ));
System.out.println(Character.UnicodeBlock.forName( "NUMBERFORMS" ));
System.out.println(Character.UnicodeBlock.forName( "MALAYALAM" ) + "\n" );
System.out.println( "Using UnicodeBlock.of(char ch) : " );
System.out.println(Character.UnicodeBlock.of( ' ' ));
System.out.println(Character.UnicodeBlock.of( '\u21ac' ) + "\n" );
System.out.println( "Using UnicodeBlock.of(int UCPoint) : " );
System.out.println(Character.UnicodeBlock.of( 1609 ));
System.out.println(Character.UnicodeBlock.of( 1565 ));
}
}

Output :
Using UnicodeBlock.forName() :
OLD_ITALIC
NUMBER_FORMS
MALAYALAM
Using UnicodeBlock.of(char ch) :
BASIC_LATIN
ARROWS
Using UnicodeBlock.of(int UCPoint) :
ARABIC
ARABIC
Note :
lang.Character.UnicodeBlock Class inherits others methods from lang.Character.Subset Class class which in turn inherits methods from lang.Character.Object class.
