The hashCode() method of a javax.naming.CompositeName class is used to return the hash code of this composite name. The hash code of this composite name object is the sum of the hash codes of the “canonicalized” forms of individual components of this composite name.

Syntax:

public int hashCode()

Parameters: This method accepts nothing.

Return value: This method returns an int representing the hash code of this name.

Below programs illustrate the CompositeName.hashCode() method:
Program 1:




// Java program to demonstrate
// CompositeName.hashCode()
  
import java.util.Properties;
import javax.naming.CompositeName;
import javax.naming.InvalidNameException;
  
public class GFG {
    public static void main(String[] args)
        throws InvalidNameException
    {
  
        // create composite name object
        CompositeName CompositeName1
            = new CompositeName("a/b/z/y/x");
  
        // apply hashCode()
        int hashCode = CompositeName1.hashCode();
  
        // print value
        System.out.println("hashCode:" + hashCode);
    }
}

Output:

hashCode:558

Program 2:




// Java program to demonstrate
// CompositeName.hashCode() method
  
import java.util.Properties;
import javax.naming.CompositeName;
import javax.naming.InvalidNameException;
  
public class GFG {
    public static void main(String[] args)
        throws InvalidNameException
    {
  
        // create composite name object
        CompositeName CompositeName1
            = new CompositeName("c/e/d/v/a/b/z/y/x/f/j");
  
        // apply hashCode()
        int hashCode = CompositeName1.hashCode();
  
        // print value
        System.out.println("hashCode:" + hashCode);
    }
}

Output:

hashCode:1184
