Java Quick Notes
Refresh Your Java - Before Java Interview
We are Agile, believe in less Documentation - Only Quick notes (Java Interview Questions) of Java/J2ee Read more....
Q) How to read both "Key" and "Value" from the Map ?
You could use "Map.Entry", which is key-value pair of the Map.
Below is the e.g.
Map<String,String>
empmapNew = new HashMap<String,String>();
empmapNewput("68688","Jones");
empmapNew.put("777777","Smith");
Set s = empmapNew.entrySet();
for(Iterator i = s.iterator();i.hasNext();){
Map.Entry me =
(Map.Entry)i.next();
System.out.println(me.getKey() + " : " +
me.getValue());
}
Map Entry
