clientlog.java

主要考察的是资源池的设计和实现

package ClientImpl;
import java.io.*;
import java.util.*;
public class ClientLog {
   
   private ArrayList list;
   private BufferedWriter writer;
   private  String filename;
   public ClientLog(String _type){
    filename=_type+".txt";
    list=new ArrayList();
    
   }

   public void Record(String time){
       list.add(time);
   }
  
   public void close() {
       try{ 
        writer=new BufferedWriter(new FileWriter(new File(filename)));
        int size=list.size();
       
            for(int i=0;i<size;++i)
            {
                writer.write(list.get(i).toString());
                writer.newLine();
            }
            
       }
       catch(Exception e)
       {
           e.printStackTrace();
       }
       finally
       {
           if(writer!=null)
            try {
                writer.close();
            } catch (IOException e1) {
                e1.printStackTrace();
            }
       }
   }
}
