These days I want to review some java classes and post them,cos i come to realize that i hava been coming to forget some of them, my god,Katrina,....:) it's really the sound,and u ? ...regarding MVC,cos be delayed, and may be will better.

List a class to use the title Properties.

import java.util.Properties;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.FileNotFoundException;
import java.io.IOException;

public class FirstDayTestProperties {
   public static void main(String[] args) throws Exception{
       Properties ProTest = new Properties();
       String  fileName="PropertiesTest.properties";
      
       try{
          ProTest.setProperty("lastDir","C:\\PropertyTest");
          ProTest.store(new FileOutputStream(fileName),null);
       }catch(IOException e){
            e.printStackTrace();
       }

       try{
          FileInputStream inStream=new FileInputStream(fileName);
          ProTest.load(inStream);
          ProTest.list(System.out);
       }catch(FileNotFoundException e){
          e.printStackTrace();
       }
   }
}
The class I just write now without any testing,but i think it seems no errors:).Share.
