Return Value: This method returns hash code for choice format object as an integer.

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)
    {
        // creating and initializing ChoiceFormat
        ChoiceFormat cf
            = new ChoiceFormat(
                "4#wed| 5#thu | 6#fri | 7#sat");
  
        // getting hashcode of  ChoiceFormat object
        // using hashCode() method
        int hash = cf.hashCode();
  
        // display the result
        System.out.print("hashCode :- " + hash);
    }
}
Output:
hashCode :- 113634 

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)
    {
        // creating and initializing limit
        double[] limit = { 1, 2, 3, 4 };
  
        // creating and initializing format
        String[] format
            = { "add", "sub", "multiply", "divide" };
  
        // creating and initializing ChoiceFormat
        ChoiceFormat cf
            = new ChoiceFormat(limit, format);
  
        // getting hashcode of  ChoiceFormat object
        // using hashCode() method
        int hash = cf.hashCode();
  
        // display the result
        System.out.print("hashCode :- " + hash);
    }
}
Output:
hashCode :- -1331463043
