The fund information fund. XML is stored in the project root directory:

<? XML version = "1.0" encoding = "UTF-8"?> <Funds> <fund id = "0"> <Name> Huaxia dashboard </Name> <code> 000011 </code> <type> hybrid </type> <URL> http://jingzhi.funds.hexun.com/000011.shtml </URL> </Fund> <fund id = "1"> <Name> Hua 'an Hongli </Name> <code> 040005 </code> <type> stock type </type> <URL> http://jingzhi.funds.hexun.com/040005.shtml </URL> </Fund> </funds>

ID or an uppercase letter "ID" as attribute.

Construct a corresponding Java Bean:

package leon.corejava.model;public class Fund {private String name;private String code;private String url;private String type;public String toString(){return this.code+"\t"+this.name+"\t"+this.url;}//getter and setter//...}

Test class:

Package Leon. corejava.
