The following Java program uses the Java JDOM Element getAttributesSize() method to get the number of attributes from the department element.

import java.io.File;
import org.jdom2.Document;
import org.jdom2.Element;
import org.jdom2.input.SAXBuilder;

public class GetAttributesSize {
   public static void main(String args[]) {
      try {	
    	 //Read the document and get the root
    	 SAXBuilder saxBuilder = new SAXBuilder();
    	 File inputFile = new File("department.xml");
    	 Document doc = saxBuilder.build(inputFile);
	     Element root = doc.getRootElement();
	     //Get attributes size
	     int attrSize = root.getAttributesSize();
	     System.out.println("Number of attributes of root : "+attrSize);       
      } catch (Exception e) {
    	 e.printStackTrace();
      }
   }
}

The output window displays the number of attributes of department element.

Number of attributes of root : 2

Example 2

The getAttributesSize() method returns '0' if there are no attributes associated with the current XML element.

import org.jdom2.Document;
import org.jdom2.Element;

public class GetAttributesSize {
   public static void main(String args[]) {
      try {	
    	 //Create Document and set root
	     Document doc = new Document();
	     Element root = new Element("root");
	     doc.setRootElement(root);
	     //Get attributes size
	     int attrSize = root.getAttributesSize();
	     System.out.println("Number of attributes of root : "+attrSize); 	          
      } catch (Exception e) {
    	 e.printStackTrace();
      }
   }
}

The number of attributes of the root element is displayed.

Number of attributes of root : 0
