The hashCode() method of java.text.Collator class is used to get the hashCode for this Collator object.
Syntax:
public abstract int hashCode()
Parameter: This method does not accept any parameter.
Return Value: This method returns hash code value in integer format.
Below are the examples to illustrate the hashCode() method:
Example 1:
Java
// Java program to demonstrate// hashCode() methodimport java.text.*;import java.util.*;import java.io.*;public class GFG { public static void main(String[] argv) { try { // Creating and initializing new simple rule String simple = "< a < b < c < d"; // Creating and initializing // new RuleBasedCollator Object RuleBasedCollator col = new RuleBasedCollator(simple); // getting hashCode of this object // using hashCode() method int hash = col.hashCode(); // display result System.out.println("hashCode is :- " + hash); } catch (ClassCastException e) { System.out.println("Exception thrown : " + e); } catch (ParseException e) { System.out.println("Exception thrown : " + e); } }} |
Output:
hashCode is :- 1882448026
Example 2:
Java
// Java program to demonstrate// hashCode() methodimport java.text.*;import java.util.*;import java.io.*;public class GFG { public static void main(String[] argv) { try { // Creating and initializing Collator Object Collator col = Collator.getInstance(Locale.UK); // getting hashCode of this object // using hashCode() method int hash = col.hashCode(); // display result System.out.println("hashCode is :- " + hash); } catch (ClassCastException e) { System.out.println("Exception thrown : " + e); } }} |
Output:
hashCode is :- 681002966
