CompoundName compareTo() method in Java with Examples

0 0 1 minute read

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");
    }
}

Output:

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");
    }
}
