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:
import java.util.Properties;
import javax.naming.CompoundName;
import javax.naming.InvalidNameException;
public class GFG {
public static void main(String[] args)
throws InvalidNameException
{
Properties props = new Properties();
props.put( "jndi.syntax.separator" , ":" );
props.put( "jndi.syntax.direction" ,
"left_to_right" );
CompoundName CompoundName1
= new CompoundName(
"a:b:z:y:x" , props);
boolean isEmpty
= CompoundName1.isEmpty();
System.out.println( "This Compound "
+ "object is empty:"
+ isEmpty);
}
}
|
Output:
This Compound object is empty:false
Program 2:
import java.util.Properties;
import javax.naming.CompoundName;
import javax.naming.InvalidNameException;
public class GFG {
public static void main(String[] args)
throws InvalidNameException
{
Properties props = new Properties();
props.put( "jndi.syntax.separator" , "/" );
props.put( "jndi.syntax.direction" ,
"left_to_right" );
CompoundName CompoundName1
= new CompoundName(
"" , props);
boolean isEmpty
= CompoundName1.isEmpty();
System.out.println( "This Compound "
+ "object is empty:"
+ isEmpty);
}
}
|
Output:
This Compound object is empty:true
