The hashCode() method of a javax.naming.CompoundName class is used to return the hash code of this compound name. The hash code of this compound name object is the sum of the hash codes of the “canonicalized” forms of individual components of this compound 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 CompoundName.hashCode() method:
Program 1:






// Java program to demonstrate
// CompoundName.hashCode()
  
import java.util.Properties;
import javax.naming.CompoundName;
import javax.naming.InvalidNameException;
  
public class GFG {
    public static void main(String[] args)
        throws InvalidNameException
    {
  
        // need properties for CompoundName
        Properties props = new Properties();
        props.put("jndi.syntax.separator", ":");
        props.put("jndi.syntax.direction",
                  "left_to_right");
  
        // create compound name object
        CompoundName CompoundName1
            = new CompoundName(
                "a:b:z:y:x", props);
  
        // apply hashCode()
        int hashCode
            = CompoundName1.hashCode();
  
        // print value
        System.out.println("hashCode:"
                           + hashCode);
    }
}
Output:
hashCode:558

Program 2:




// Java program to demonstrate
// CompoundName.hashCode() method
  
import java.util.Properties;
import javax.naming.CompoundName;
import javax.naming.InvalidNameException;
  
public class GFG {
    public static void main(String[] args)
        throws InvalidNameException
    {
  
        // need properties for CompoundName
        Properties props = new Properties();
        props.put("jndi.syntax.separator", "/");
        props.put("jndi.syntax.direction",
                  "left_to_right");
  
        // create compound name object
        CompoundName CompoundName1
            = new CompoundName(
                "c/e/d/v/a/b/z/y/x/f",
                props);
  
        // apply hashCode()
        int hashCode
            = CompoundName1.hashCode();
  
        // print value
        System.out.println("hashCode:"
                           + hashCode);
    }
}
Output:
hashCode:1078
