From .Net foreach KeyValuePair to Java Equivalent

public Set entrySet()

The entries in the returned Set are of type Map.Entry.

When working with the Set returned from entrySet(), you already have both the key and value together:

import java.util.Hashtable; import java.util.Iterator; import java.util.Map; import java.util.Set; public class MainClass {   public static void main(String[] s) {     Hashtable table = new Hashtable();     table.put("key1", "value1");     table.put("key2", "value2");     table.put("key3", "value3");     Set set = table.entrySet();     Iterator it = set.iterator();     while (it.hasNext()) {       Map.Entry entry = (Map.Entry) it.next();       System.out.println(entry.getKey() + " : " + entry.getValue());     }   } }

Porting C# to Java

1. Enum => EnumType
2. Get/Set=>get_XXX/Set_XXX
3. Dataset/Datarow=>Result?
4. MessageQ=>RabbitMQ or ActiveMQ
5. Event =>Listener
6. bool=>boolean
7. string=>String
8. Tcplistener=>Serversocket
9. str.Length=>str.length
10. str.Substring=>str.substring
11. Lock()=>synchronized
12. DateTime.Now=>Calendar.getinstance().getTime()
13. byte.ToString("X2")=>String.format("%02X", byte)
14. Environment.CurrentDirectory=>

    new java.io.File( "." ).getCanonicalPath()/System.getProperty("user.dir") 

15. new Queue()=>new LinkedList()

The RabbitMQ Java client library allows Java code to interface to AMQP servers
