i just want to make 2d animation which method i should use ? or should i mix some of them while work
To the question: "which technique to use"
The answer that I'd give is: Flash/Animate is most famous and best suited for digital cutout animation using Graphic Symbols and Classic Tweens.
You can also do frame-by-frame.
As to what these terms mean... well... there are a lot of books, articles and materials on the matter in the bookshops and online.
any video examples on how the rsults of
cutout animation using Graphic Symbols and Classic Tweens.
And because you are asking for examples/manuals for frame-by-frame animations, this page Frame-by-frame animation with Animate CC might be good for you. It contains also a chapter about Onion Skinning which is an essential work method in frame-by-frame techniques.
Consider, on all pages of this kind you find at the very bottom (scroll down) a function/link called Change Region. Here I hope you find a version of your language.
