[Java] Reflection

[ally]

...ciao...

...sto smanacciando un po' con la reflection...

public static void main(String[] args) {
        
        createObject("it.ally.Test");
     }

     static Object createObject(String className) {
        Object object = null;
        try {
            Class classDefinition = Class.forName(className);
            classDefinition.newInstance();
        } catch (Exception e) {
            System.out.println(e);
        } 
        return object;
     }

public class Test {
    
    public Test(){
        
        System.out.println("reflection!");
        
    }

    public Test(String arguments){
        
        System.out.println(arguments);
        
    }
    
}

...come è possibile passare argomenti nel momento di istanziare la classe?

...ciao Andrea...

...dopo un po' di strani smanacciamenti :

public static void main(String[] args) {

           Class reflectionClass;
           Class[] intArgsClass = new Class[] {String.class};
           String string = "ciao";
           Object[] intArgs = new Object[] {string};
           Constructor intArgsConstructor;

           try {
               reflectionClass = Class.forName("it.ally.Test");
             intArgsConstructor = reflectionClass.getConstructor(intArgsClass);
             createObject(intArgsConstructor, intArgs);
           } catch (ClassNotFoundException e) {
               System.out.println(e);
           } catch (NoSuchMethodException e) {
               System.out.println(e);
           }
        }

        public static Object createObject(Constructor constructor, 
                                          Object[] arguments) {

           System.out.println ("Constructor: " + constructor.toString());
           Object object = null;

           try {
             object = constructor.newInstance(arguments);
             System.out.println ("Object: " + object.toString());
             return object;
           } catch (Exception e) {
               System.out.println(e);
           } 
           return object;
        }

...la mia idea sarebbe di implementare la reflection per un sistema multi thread...avete idee o opinioni sull'uso migliore della reflection?...

...ciao Andrea...
