The compareTo() method of a javax.naming.CompoundName class is used to compare this CompoundName with the specified object passed as a parameter. It returns a negative integer, zero, or a positive integer as this CompoundName object is less than, equal to, or greater than the given Object as a parameter. If the passed object is null or not an instance of CompoundName then the ClassCastException is thrown by this method.
Syntax:
public int compareTo(Object obj)
Parameters: This method accepts obj which is the non-null object to compare against.
Return value: This method returns a negative integer, zero, or a positive integer as this Name is less than, equal to, or greater than the given Object.
Exception: This method throw ClassCastException if passed obj is not a CompoundName object.
Below programs illustrate the CompoundName.compareTo() method:
Program 1:
// Java program to demonstrate // CompoundName.compareTo() 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( "x:y:z" , props); CompoundName CompoundName2 = new CompoundName( "x:y:m" , props); // apply compareTo() int value = CompoundName1 .compareTo(CompoundName2); // print value if (value > 0 ) System.out.println( "CompoundName1 is " + "greater than CompoundName2" ); else if (value < 0 ) System.out.println( "CompoundName1 is " + "smaller than CompoundName2" ); else System.out.println( "CompoundName1 is " + "equal to CompoundName2" ); } } |
CompoundName1 is greater than CompoundName2
Program 2:
// Java program to demonstrate // CompoundName.compareTo() 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( "x@y@z@M@n" , props); CompoundName CompoundName2 = new CompoundName( "x@y@z@M@n" , props); // apply compareTo() int value = CompoundName1 .compareTo(CompoundName2); // print value if (value > 0 ) System.out.println( "CompoundName1 is " + "greater than CompoundName2" ); else if (value < 0 ) System.out.println( "CompoundName1 is " + "smaller than CompoundName2" ); else System.out.println( "CompoundName1 is " + "equal to CompoundName2" ); } } |
CompoundName1 is equal to CompoundName2
