Java getting array's name

Question

Hello programmers!

Is it possible to get the array's name in java?

For example

Int[] age = {12, 13, 14, 15};

System.out.println(age.getName());//something like this

//[Excepted Output]: age

____________________________
Why I want this?

I have 2d object array, where I stored all my arrays in it... Now Im trying to get that array's name just by calling it

Like
_________________________________

Object [][] student = {array1, array2, array3};

System.out.println(student[2].getName());

//Excepted Output]: array2

Thank you 😊!

Happy coding!

Answer 1

If your variable is a field you can use
getDeclaredFields() on the class and then on the corresponding field getName().

But as Avinesh stated if you need to use reflections it's almost always a hint that your design isn't the best approach. You should try to refactor the code to avoid the reflection.

Lily Mea yeah I got it... But what about my 2nd example? It wont work there

Thanks!

Answer 3

Avinesh oh thanks!

Answer 4

Getting an array name is not possible in your first example. In your second example, you are again trying to access the name of the array which is again not possible. The Reflection API might be helpful but is not recommended to use.

Trying to print a reference variable will print 'ClassName@HashCode' and you can probably override the toString() to get a result according to your need.

looking at this is kinda weird,because
if u can get the arrays name like this
age.getName() = age
then,in order to get the array's name,u need the array's name..
got it?
