How can i switch a variable name in the Update ?

using System.Collections.Generic;
using UnityEngine;


public class SwtichName : MonoBehaviour
{
    [SerializeField]
   
    [Space(5)]
    [Header("Rotation Mode")]
    public bool individualRotation = false;

    private void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if (globalRotation == false)
        {
           // Name in inspector should be individualRotation
        }
        else
        {
            // Name in inspector should be globalRotation
        }
    }
}

I want to switch the string name of the variable in the Update when checking/unchecking the variable:

public bool individualRotation = false;

If not checked(false) the name should be individualRotation.
But if checked(true) i want that the name will be globalRotation.

I think you want an enum.

using System.Collections.Generic;
using UnityEngine;

public class SwtichName : MonoBehaviour
{

    public enum RotationMode
    {
        Individual,
        Global
    }

    public RotationMode rotationMode;


    private void Start()
    {
      
    }

}

And how do i change the variable name ?
I have a bool variable name individualRotation
How do i change it’s name to Individual or Global ?
I can use switch and case but how do i change the variable name ?

Why do you need two of them? It’s a boolean! It has 2 possible values. Why do you never use the other one?
If individualRotation is true then does that not nean globalRotation is false?

There, I’ll do some more spoonfeeding:
Your (recommended) new update():

// Update is called once per frame
    void Update()
    {
        if (individualRotation== true)//this means globalRotation is false
        {
           // Name in inspector should be individualRotation <- NO! NO! Bad newbie programmer! Bad!
        }
        else//this means globalRotation is true
        {
            // Name in inspector should be globalRotation <- NO! NO! Bad newbie programmer! Bad!
        }
    }
