java如何取出map中的键和值的例子。

package wzq.j2se;

import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import java.util.Set;

public class MapDemo {

/**
* @param args
*/
public static void main(String[] args) {
Map map = new HashMap();
map.put(“name”, “wzq”);
map.put(“pswd”, “zzzzzz”);
Set keySet = map.keySet();
for (Iterator<?> iter = keySet.iterator(); iter.hasNext();){
String key = (String) iter.next();
System.out.println(“key==”+key);
String value = (String) map.get(key);
System.out.println(“value==”+value);
System.out.println(“”);
}
}

}
