testhashmap.java

我初学java时两个星期写的源代码

package com.softeem.jbs;

import java.util.Enumeration;
import java.util.HashMap;
import java.util.Properties;

public class TestHashMap {

	public static void main(String[] args) {
		Properties props = System.getProperties();
		HashMap map = new HashMap();
		Enumeration e = props.propertyNames();
		while (e.hasMoreElements()) {
			String key = (String) e.nextElement();
			String value = props.getProperty(key);
			//    	 System.out.println(key + "=" + value);
			map.put(key, value);
			System.out.println(map.get(key));

		}
	}

}
