The hashCode() method of java.text.RuleBasedCollator 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 program to demonstrate
// hashCode() method
import 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 program to demonstrate
// hashCode() method
import 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 < c & a < b";
// 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 :- 2022902017
