package pkg;  
  
import java.io.FileInputStream;  
import java.io.IOException;  
import java.io.InputStream;  
import java.util.Properties;  
  
public class PTest {  
    public static void main(String[] args) {  
        try {  
            long start = System.currentTimeMillis();  
            InputStream is = new FileInputStream("D:\\workspace\\cdt\\2\\test\\src\\pkg\\conf.properties");  
            Properties p = new Properties();  
            p.load(is);  
            is.close();  
            System.out.println("SIZE : " + p.size());  
            System.out.println("homepage : " + p.getProperty("homepage"));  
            System.out.println("author : " + p.getProperty("author"));

            System.out.println("date : " + p.getProperty("date"));  
            long end = System.currentTimeMillis();   
            System.out.println("Cost : " + (end - start));  
        } catch (IOException ioe) {  
            ioe.printStackTrace();
