android sax parser handler

Question

I have to develop one xml parsing app using sax parser.

I have follows below xml feed:

<root>
  <Categories>
        <Category name="Photos">
             <article articleid="4537" title="Sonam-Steals-the-Mai-Show"/>
             <article articleid="4560" title="Big-B-Croons-For-World-Peace"/>
              <article articleid="4585" title="Yami-Paints-The-Town-Red"/>
         </Category>
       <Category name="Style">
             <article articleid="266" title="Dita wows us in a sari"/>
             <article articleid="268" title="Frieda is a natural"/>
             <article articleid="269" title="Demi finds love in Jodhpur"/>
       </Category>
    </Categories>
    </root>

Here i have to create one class for getter and setter:

public class Laptop {
            private String brand;
            private List<String> model;
          public String getBrand() {
           return brand;
             }

       public void setBrand(String brand) {
               this.brand = brand;
                }
         public List<String> getModel() {
          return model;
           }
        public void setModel(List<String> string) {
          this.model = string;
         } 

My xml handler look like below code:

public void startElement(String uri, String localName, String qName,
        Attributes attributes) throws SAXException {
    current = true;
        if (localName.equals("Category")) {
        laptop = new Laptop();
        laptop.setBrand(attributes.getValue("name"));

    }

     else if (localName.equals("article")) {
           laptop.setModel(attributes.getValue("title"));
       } 
        }

public void characters(char[] ch, int start, int length)
        throws SAXException {
    if(current)
    {
        currentValue = new String(ch, start, length);
        current=false;
    }
         }

     public void endElement(String uri, String localName, String qName)
        throws SAXException {
          current = false;
      if (localName.equals("Category")) {
          // add it to the list
          laptops.add(laptop);

      } 
    if (localName.equals("article")) {
        laptop.getModel().add(currentValue);
        } 

Here am getting below error on these line:

           laptop.setModel(attributes.getValue("title"));

The method setModel(List) in the type Laptop is not applicable for the arguments (String)

How can i resolve that error.please give me solution for these...

Answer 1

The error says yon can not assing a String instance to a List instance. And it is quite reasonable. Since

public void setModel(List<String> string) {
          this.model = string;
} 

takes a List as parameter.

As possible fix you can try in this way, if you want to keep a List of String (article) for every Laptop instance

public void setModel(String string) {
      if (this.model == null)
           this.model = new List<String>();    
      this.model.add(string);
}
