testproperties.java

用java编写的一些初级代码

import java.util.*;
public class TestProperties{ 
    public static void main(String args[]){ 
	Properties sp=System.getProperties();
	Enumeration e=sp.propertyNames();
	while(e.hasMoreElements())
	{
	    String key=(String)e.nextElement();    
	    System.out.println(key+" = "+sp.getProperty(key));
	}
    }
}
