What is the use of a local class in java

Question

is it really useful at all?

Answer 1

ifl hi,
A local inner class will have access to all the members of the enclosing class and it’ll have access to the local final variables in the scope it’s defined.
I think use of local class somehow on specific situation is required where we have to hide our data from outside of class like I have some examples from which I will try to explain you
1) first I take an example encoder decoder project => in this project I have to hide the encryption at encoder side and decryption at decoder side if I create two local classes which store and secure that data for me
2) in microprocessor all codes have some op codes so if I have to make microprocessor then I just create an local class and do everything op codes store in that class which is not accessible outside the class

I hope this link can help you I'm not good in explaining

Haha, I feel honored.
Let me just refer to the official tutorial, because it covers the topic perfectly.
The official tutorial is sometimes a little confusing and often long to read, but this chapter is really good.
Just ask if you have any further questions on the matter.

ifl may be this link can help you about local class use

Answer 4

GAWEN STEASY yes, thanks for the post. I saw it (or similar ) in quora, but I never felt I the need to use this myself, so checking what people think, or how it is used in real examples...
:-)

Answer 5

well thanks but yeah if someone good in Java like Tashi N if she do share some knowledge on this then It would be good just in case she is free tagging you for the thread

Answer 6

Mohit the coder (M.S.D) Interesting examples, thanks.

Answer 7

Thanks Tashi N !

Answer 8

For example: I used it in a blockchain application, in the blockchain class I made a seperate inner class mining. This makes the code more clean and readable.

Can be very usefull for testing/benchmarking as well.
