Character.Subset Class represents particular subsets of the Unicode(standards using hexadecimal values to express characters - 16bit) character set. The subset, it defines in Character set is UnicodeBlock.
Declaration :
Java
Output :
public static class Character.Subset extends ObjectConstructors :
- protected Character.Subset(String str) : Constructs new subset instance.
- equals() : java.lang.Character.Subset.equals() tells whether the two Subset Object are equal or not.
Syntax :
public final boolean equals(Object o) Parameters : o : object to be compare with. Return : true : if o equals argumented object, else false.
- hashCode() : java.lang.Character.Subset.hashCode() returns the hashCode value of the Subset..
Syntax :
public final int hashCode() Parameters : --- Return : hashCode of the argumented object.
- toString(): java.lang.Character.Subset.toString() returns name of the Subset.
Syntax :
public final String toString() Parameters : --- Return : string representation of the argumented object.
