How to use only one method for any data type

Question

https://code.sololearn.com/cwKAoMXo7tbZ/?ref=app
here, I have made a class with a random function that takes an array argument and returns a random element of that array.
Is there a better way to write, without having to overload for different data types?

Answer 1

Edited:

You can try to generify your static random method in your Select class. That way you can use one method for any data type without explicitly instantiating the Select class.

【ＡＣＥ】 you're welcome.

I'll still follow this thread to see if someone else can come up with better solutions.. 😅

Answer 3

Sigag Thanks, Is it possible to use the static method of generic class, so that we don't have to explicitely instantiate or state the data type.

Answer 4

Sigag Thanks a lot, ur code have been really helpful.

Martin Taylor Thank you for your input! Your contribution to community has always been very helpful!

Actually the OP asked "..without having to overload for different data types"
I couldn't understand how to do it for primitive types so did it for reference types instead 😅

Is there any way to achieve this for primitive types without using overloaded methods?

Answer 6

Martin Taylor thanks, I saw the API for Arrays.binarySearch, was surprised to see overloading for different data types.
