Using one variable as an another variable of different data type but the same name
===

I am using a class where I am taking input as the file name and the file location. I have a pre defined file names, so I will match the predefined file names with the file name that I received and then store the values accordingly. Please look at the code below 

    //Set of storage maps and tables 
    public class storage
    {
    //Storage set
    public static Set<Integer> tiger = new HashSet<Integer>();
 
    //Storage set
    public static Set<Integer> lion = new HashSet<Integer>();

    //This is the table used for storing the browser customer count  
    public static Table<String,String,Integer> elephant = HashBasedTable.create(); 

    //Storage map 
    public static Map<String, String> monkey = new HashMap<String, String>();


    public static void storeDataDirector(String fileLocation,String fileName) throws     Exception 
    {
        if (fileName = monkey) 
                    **update the "monkey map"**

    }

This is my problem, also I have lot of maps and tables to be used so I wouldn't be able to use multiple if conditions and then check and update the same.

What I would like to know is the below 

As I have said earlier, The file name that I am sending to the program which is "String filename" has the same name of the "Map<String, String> monkey" but the former is a String and the latter is the map. **I would like to know if I will be able to use the string variable as a reference to the map instance as both of them have the same name** . This will highly avoid the if conditions that I am using in the program and thus I would like to possible solution for this ... Anything related to type caseting ort
