后缀名为properties,config和xml的文件内容读取
1、先建立文件(后缀名为properties和config)
2、读取类建立
public class Read{
public static Properties properties = new Properties();
static {
tr{
properties.load(new FileReader(src/type.properties));
}catch(Exception e){
e.printStackTrace();
}
}
public static void main(String[] args){
//方式一
String type = properties.getProperty("type");
TVFactory tvFactory = (TVFactory)Class.forName(type).newInstance();
TV tv = tvFactory.produceTV();
tv.pay();
//方式二(xml的读取)
SAXReader reader = new SAXReader();
Document document = reader.read(new File(src/tv.xml));
Element config = document.getRootElement();
Iterator it = config.elementIterator();
String str = null;
while(it.hasNext){
Element type = it.next();
str = type.getStringValue();
}
TVFactory tvFactory = (TVFactory)Class.forName(type).newInstance();
TV tv = tvFactory.produceTV();
tv.pay();
}
}
