Polymorphism and creation of Object using String

It should give compilation error:

Cannot reduce the visibility of the inherited method from One

Try to make method as public.

public class Two implements One{
    private int no;

    public void setNo(int no){ = no;

I don't know where are you created Three class, but I can help with your Two class.

public class Two implements One {
     private int no;

        public void setNo(int no){
   = no;
        public static void main(String[] args) {
            One base;

            Class c;
            try {
                c =
                base = (One) c.newInstance();
            } catch (ClassNotFoundException e) {
                // TODO Auto-generated catch block
            } catch (InstantiationException e) {
                // TODO Auto-generated catch block
            } catch (IllegalAccessException e) {
                // TODO Auto-generated catch block

c# object behaviour with polymorphism
Your approach is not bad, although you should declare mergeA and mergeB functions as protected since they should not be exposed, but you would need some type check and casting before calling mergeA and mergeB. Another approach would be defining this in the base class (without overloading any of these functions): public abstract class Base { public int val {get;set;} public bool merge(Base

Preventing object class creation
You missed this bit: by declaring at least one constructor That's what's preventing the default constructor from being created. The example given has a default access (package access) constructor: PackageOnly() { } ... so it satisfies both conditions: a) it declares at least one constructor; b) it declares no public constructors.

Multi threaded access to map object that won't be modified after creation
Why don't you try an ImmutableMap? Once created cannot be modified so doesn't matter how many threads try to read in parallel.

Inherit construction logic, but run Super constructor on Sub object creation
When you want subclassing, consider using function Constructor() { SuperConstructor.apply(this); /* ... */ } Constructor.prototype = Object.create(SuperConstructor.prototype); Object.defineProperty(Constructor.prototype, 'constructor', { value: Constructor, configurable: true, writable: true }); Calling SuperConstructor inside Constructor makes Constructor instances have pr

Javascript creation of unique copy of given string text
Check this fiddle out. The main part is like following (you need underscore.js) function do_it(input, final_arr){ var SUF = ' - Copy' // input text is first occurence in final_arr if(!_(final_arr).contains(input)){ return input } // input text is the second occurence in final_arr var copied = input + SUF if(!_(final_arr
