Inner Class

[Nelson Nadal]

Just thinking... is there a way that I can call the class A (the one outside the TestClass) in main method? The codes here is only in a single file. Thanks.

  
class A
{
public void m(){System.out.println("indep class A");}
}
public class TestClass 
{

public class A
{
public void m() {System.out.println("Inner class A"); }
}
class B extends A
{
}

public static void main(String args[])
{
TestClass.A iA = new TestClass().new A();
iA.m();
//Codes here...
}
}

Not without using reflection and a factory class, but then that begs the question, why not either rename the outer class A or better put it in a separate package and file. The inner class A hides the outer class just like a method local variable with the same name as an instance variable will hide it.
Here's a reflection solution:

import java.lang.reflect.*;
class A {
    public void m() {
        System.out.println("indep class A");
    }
}
class AFactory {
    public static A getAInstance() {
        return new A();
    }
}

public class TestClass {
    class A  {
        public void m() {
            System.out.println("Inner class A");
        }
    }
    class B extends A  {}
    public Object getExteriorInstance() {
        return new A();
    }
    public static void main(String args[])  {
        TestClass.A iA = new TestClass().new A();
        iA.m();
        Object a = AFactory.getAInstance();
        try {
            Method m = a.getClass().getDeclaredMethod("m", null);
            m.invoke(a, null);
        } catch (NoSuchMethodException     ignore) {}
          catch (IllegalAccessException    ignore) {}
          catch (InvocationTargetException ignore) {}
    }
}
