Hello at the Ranch:

I have a simple question regarding PropertyUtils --> PropertyDescriptors


Please consider the code below:
It produces the following output:
After you get the classpath correct. fun fun fun

Hello from TestPropUtil
propDesc.length: 7

propName: class
propType: class java.lang.Class

propName: dressName
propType: class java.lang.String

propName: dressPartCodes
propType: class [Ljava.lang.String;

propName: dressPartNames
propType: class java.util.HashMap

propName: dressSampleArrived
propType: class java.util.Date

propName: dressSampleOrdered
propType: class java.lang.Integer

propName: dressType
propType: class java.lang.String


In the above output what is the propName: class related to the class Dress "as a whole".
More important this:
propName: dressPartCodes
propType: class [Ljava.lang.String;
The property type in the class definition is String[], this kinda gave me pause.
Not what I was expecting. Can someone take a shot at explaining [Ljava.lang.String;

Many thanks for your kind assistance.

I don't know what that means. Can you try to ask it again in a different way?

That is the way String[] is written as a type. The [L means "array of type" then the java.lang.String provides the type of data held in the array.
