Enumerating Strings in Java with For Loop

Question

Having trouble getting this for loop w/ enumerated strings to compile, I don't know what I'm missing to make it work. I prefer using for (i = 0; i < 5; i++) {} but it doesn't work well for strings. Any advice is appreciated.

import java.util.*`

  public class Main { 
    public static void main(String args[]) 
    { 
        Enumeration<String> Names; 
        Vector<String> cNames = new Vector();
        Names.add("string1"); 
        Names.add("string2"); 
        Names.add("string3"); 
        Names.add("string4"); 
        Names.add("string5");
        Names = cNames.elements();
        for (Names : cNames.elements())
        { 
            System.out.println(names); 
        } 
    } 
}

`for (String names : Names.elements())` - and you have a `Vector` with that name - you can't also name `Enumeration` `Names` (which looks like a class, not a variable). — Elliott Frisch, Oct 03 '17 at 21:59
And you aren't using generics, and you shouldn't use `Vector` or `Enumeration`... — chrylis -cautiouslyoptimistic-, Oct 03 '17 at 22:32

Names is already defined in scope. You have Enumeration Names and Vector Names

you might want to name them differently, and naming convention should start with lower case.

I edited it, missed a typo from my IDE code. Stack Overflow doesn't show my s after "Enumeration" & "Vector" either – Squilly Oct 03 '17 at 22:06
You want to instantiate Your typed enumeration. `Enumeration Names = new Enumeration() {}` – Akin Okegbile Oct 03 '17 at 22:13
This question talks about List of Enums Which is what i assume you're trying to do . A Vector of Enum values https://stackoverflow.com/questions/2849529/java-enum-list-from-class – Akin Okegbile Oct 03 '17 at 22:25
