Is there away to generate Variables' names dynamically in Java?

Question

Let\'s say that I need to generate variables to hold some input from the user (I don\'t know how many they are). Without using Array, ArrayList (an

Answer 1

You mean you want to generate variables named

var0, var1, var2 and use them in your code.

What is the difference when you use var[0], var[1], var[2], .....

BUT

You can generate a Java class dynamically at runtime which implements an Interface you are using in your normal code. Then you compile this class using a compiler (For example Janino) and then load the class at runtime. Than you have created a class dynamically.

But i wonder, whether this is necessary for your usecase.

EDIT

I dont now for which usecase you are using this parameters but dynamic arguments you can use in Java like this example from here

// calculate average
        public static double average( double... numbers )
        {
           double total = 0.0; // initialize total

          // calculate total using the enhanced for statement
          for ( double d : numbers )              
             total += d;                          

          return total / numbers.length;
       } // end method average
