Question

I would like to see if I can avoid a lengthy switch or if block by directly converting some strings into an object name. For example, I have a class called Example and I want to [edit] have up to 10 instances of the class Example1, Example2, so on. Can I use something like:

  int ExampleNum = 2;    
// can be changed to any 1-10 value corresponding to instances
    String s = "Example" + String.valueOf(ExampleNum);

Refresh(s);

public void Refresh(Example example){
...
}

Thus I would create a string with the value of Example2 and pass that to my Refresh method.

[edit]
I don’t want to use all the instances at once, but rather have other methods that change the int ExampleNum so that when I try to refresh it refreshes the appropriate Example instance.

Rather than saying:

if (ExampleNum == 2)
    Refresh(Example2);

I would use the ExampleNum and String to use the right instance name;

Answer 1

Why not use array’s instead??

Example[] e = null;
    for(int i=1;i<=10;i++)
    {
        e[i] = new Example();
        Refresh(e[i]);
    }
