CompoundName isEmpty() method in Java with Examples

Last Updated : 27 Mar, 2020

The isEmpty() method of a javax.naming.CompoundName class is used to check this compound name object is empty or not. A compound name is said to be empty if it has zero components. Syntax:

public boolean isEmpty()

Parameters: This method accepts nothing. Return value: This method returns true if this compound name is empty, false otherwise. Below programs illustrate the CompoundName.isEmpty() method: Program 1:

Java

// Java program to demonstrate
// CompoundName.isEmpty()

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 isEmpty()
        boolean isEmpty
            = CompoundName1.isEmpty();

        // print value
        System.out.println("This Compound "
                           + "object is empty:"
                           + isEmpty);
    }
}

Output:

This Compound object is empty:false

Program 2:

Java

// Java program to demonstrate
// CompoundName.isEmpty() 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(
                "", props);

        // apply isEmpty()
        boolean isEmpty
            = CompoundName1.isEmpty();

        // print value
        System.out.println("This Compound "
                           + "object is empty:"
                           + isEmpty);
    }
}
