Last Updated : 13 Sep, 2023

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.

public static class Character.Subset
   extends Object

• 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.
  

// Java Program illustrating the use of Character.Subset class Methods.

import java.lang.*;

public class CharacterSubsetDemo extends Character.Subset 
{
   CharacterSubsetDemo(String s) 
   {
      // Use of super keyword : 
      // Invokes immediate parent class constructor.
      super(s); 
   }

   public static void main(String[] args) 
   {
      // Initializing two Subsets.
      CharacterSubsetDemo a = new CharacterSubsetDemo("geeks");
      CharacterSubsetDemo b = new CharacterSubsetDemo("for");

      // use of equals() : 
      boolean check2 = a.equals(a);
      System.out.println("Is a equals a ? : " + check2);
      check2 = b.equals(a);
      System.out.println("Is b equals a ? : " + check2);
      System.out.println();
      
      // Use of hashCode() : 
      int check1 = a.hashCode();
      System.out.println("hashCode " + a + " : " + check1);
      check1 = b.hashCode();
      System.out.println("hashCode " + b + " : " + check1);
      System.out.println();
      
      // Use of toString() : 
      System.out.println("a : " + a.toString());
      System.out.println("b : " + b.toString());
   }
} 

Is a equals a ? : true
Is b equals a ? : false

hashCode geeks : 366712642
hashCode for : 1829164700

a : geeks
b : for
