CompositeName isEmpty() method in Java with Examples

Last Updated : 27 Mar, 2020

The isEmpty() method of a javax.naming.CompositeName class is used to check this composite name object is empty or not. A composite 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 composite name is empty, false otherwise. Below programs illustrate the CompositeName.isEmpty() method: Program 1:

Java

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

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 isEmpty()
        boolean isEmpty
            = CompositeName1.isEmpty();

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

Output:

This composite object is empty: false

Program 2:

Java

// Java program to demonstrate
// CompositeName.isEmpty() 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("");

        // apply isEmpty()
        boolean isEmpty
            = CompositeName1.isEmpty();

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

Output:

This composite object is empty: true
