You need to create objects within the HelloTester class. The code you submitted:
class HelloTester
{
public static void main ( String[] args )
{
HelloObject anObject = new HelloObject("A Greeting!");
anObject.speak();
}
}
creates 1 object referenced by 'anObject'. You can create the remaining objects, either by creating more objects as above, but changing the variable name that references the object. i.e. 'anotherObject', or if you have been taught it yet, use loop conditions. i.e for loop.
if you are unsure of creating the objects, within your main() method:
class HelloTester
{
public static void main ( String[] args )
{
HelloObject anObject = new HelloObject("A Greeting!");
anObject.speak();
HelloObject anotherObject = new HelloObject("Another Greeting!");
anotherObject.speak();
// the remaining objects would be put underneath.
}
}
