QUESTION
This is my first attempt at parsing nested JSON with Ruby. I need to go through the JSON to pull out specific values for "_id", "name", and "type" for instance. I then need to create a reference table so that I can refer to each "_id" and associated information. I also need to combine information from multiple JSON responses. I've been able to get basic information and have tried a few things I've found online. I just need a little assistance with a starting point. If anyone has any ideas of where to start with this I'd really appreciate it.
Devices JSON response hash. Each device starts with _id.

QUESTION
I have a problem with xslt in 1.0 version. My node looks like this
...ANSWER
Answered 2021-May-18 at 20:24In XSLT 1.0, the xsl:value-of
instruction creates a text node whose value is the string-value of the first node in the selected node-set.
In your example, the $entries
variable is a result-tree-fragment that contains the text "red yellow left"
(with or without some white-space characters). In order to process a result-tree-fragment using the xsl:for-each
instruction, you must first convert it to a node-set, using a processor-specific extension function. In any case, it wouldn't do you any good in this case, since - as explained above - it contains a single text node.
QUESTION
I am testing inheritance within Java, I have an abstract class with two fields and three extended classes with their own fields. In another class I instantiate and add objects of the class in an array, but I am not sure of how I can access the fields of the subclasses, the array is of the main abstract class:
here is the complete code of the abstract class and one of the extended classes:

The java type system is covariant. (Except in generics, where variance is selectable, and by default, invariant). For the rest of this answer, you need to be aware that:
- java.lang.Integer extends java.lang.Number
- java.lang.Double extends java.lang.Number
- java.lang.Number extends java.lang.Object
Covariance means that you can take an expression whose type is Integer
, and use it where a Number
is required: Any subtype is fine when a supertype is required. (Invariance means that only an expression of specifically type Number will do, and contravariance is the reverse: If Integer is required, either Number or Object is also fine).
Thus:

You can get it even simpler, by accessing the exact property you need. For example, to display the value of "motoBrand" property, please use the following lines of code:
