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 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 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);    }} |
Output:
This Compound object is empty:true
