dosyaları bulunduğu klasöre kopyalar programı restart edip dll’i host eder.

Java XML Serialization

Java XML Serialization için bir örnek

import java.io.StringWriter;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name=”XmlClass“)
public class XmlClass {
@XmlElement(name=”XmlNode“)
public String XmlNode=”xml node“;

public SubNode SubNodeObject=new SubNode();

public static void main(String args[]){
try{
XmlClass serializer=new XmlClass();
JAXBContext context = JAXBContext.newInstance(serializer.getClass());
Marshaller marshaller = context.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
StringWriter xmlInfo=new StringWriter();
marshaller.marshal(serializer,xmlInfo);
System.out.println(xmlInfo);
}
catch(Exception ex){
ex.printStackTrace();
}
}

}
@XmlRootElement(name=”SubXmlClass“)
public class SubNode{
@XmlElement(name=”SubXmlNode“)
public String XmlNode=”sub xml node“;
}

Kod çıktısı

<?xml version=”1.0″ encoding=”UTF-8″ standalone=”yes”?>
<XmlClass>
<XmlNode>xml node</XmlNode>
<SubNodeObject>
<SubXmlNode>sub xml node</SubXmlNode>
</SubNodeObject>
</XmlClass>

C# 3.0 var kullanımı

C# 3.0 ile gelen var tanımlayıcısının kullanımı

var sayi=10;  (sayi değişkeni sayısal bir veri tuttuğu için sayısal bir değişken olarak kullanılır)

var metin=”serdar türkel”; ( metin değişkenine metinsel bir değer atandığı için metin değişkeni bir karakter dizisi olarak kullanılır )

var değişkeni ile değişkenlerin veri tipleri yürütme zamanında (runtime) belirlenir.

var kisi = new { Ad = “serdar”, Soyad = “türkel” }; (kisi sınıfsal bir veri türü olarak belirlenir. “ad”, “soyad” ise  bu sınıfa ait özellikleri göstermektedir.)
