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 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 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
