Question

I am using the tutorial here for understanding JAXB.

When the writer comes to create the root of the document, the writer begins as below:

//This sta         


        

Answer 1

• @XmlRootElement annotation can be used to map a class or enum type to XML type.

• When a top level class or an enum type is annotated with the @XmlRootElement annotation, then its value is represented as XML element in an XML document.

• Follow the example given below to get more idea:

Associate an element with XML Schema type

// Example: Code fragment
 @XmlRootElement
 class Point {
    int x;
    int y;
    Point(int _x,int _y) {x=_x;y=_y;}
 }

 //Example: Code fragment corresponding to XML output
 marshal( new Point(3,5), System.out);
