I have a class A, with two variable varOne, varTwo,
While assigning I only assigned varTwo, but when converting to JSON I'm getting both the value
one which was unassigned is as null.
What can I do to restrict varOne. if varOne is unassigned the I don't want it at all in Json.
I tried reconstruct the JSON. but feels like could do better.
You can put #JsonInclude(JsonInclude.Include.NON_NULL) above the class

So i need the following values: Values
I want to get them and save them in a variable for example. Do you have any suggestions for me ?
I want to get them to save the last position of an element. :)
if you have access to your element you can use a reference to it with a ViewChild for example https://angular.io/api/core/ViewChild and then you can use
myElementRef.style.transform
This will only give you a string containing the value of the property transform. If you want to access the values you would have to parse the string.

The response to a REST web service has a field of type Double. If its value is '0.0' that field is not appearing in JSON response
Try using #JsonInclude(Include.ALWAYS) as javadoc says
property is to be always included, independent of value of the
property

For example, I have my main method as well as the method returnOdds(original), that returns the integer array "odd"
How would I print the elements of this array in the main method? With a for loop?
A for loop would work. If you don't care about the format, though, a simpler solution might be to use Arrays.toString, which will convert in the form "[elem1, elem2, ..., elemn]".
"With a for loop?"
answer : "yes"
