Really need some help been stuck all day on this

Question

ok i'm abit confused I've been stuck on this problem all day and would appreciate your help
Classes Animal, tiger, lion etc all have constructors that take values and work
I'm trying to create an array of animals eg different types and display them all together using a toString
All ive managed to do was get a memoryaddress of the object
I have multiple classes eg abstract base class Animal Tiger extends Animal Lion extends Animal etc
Animal is abstract and has an abstract String toString method
All the derived classes have String toString methods that returns a description
how do i put them all together in arrays and call the string toString for all the different animals
public void displayMethod()
println(objectname);
I have tested the constructors for all classes using a single instance and they work it's just puting them all together in an array and then displaying all the different animals using each classes toString

You are nearly there!
for (int i=0; i<animals.length; i++)
  System.out.println(animals.toString());
}Note the use of animals.length in the for loop. This guarantees you only loop over the number of objects in the array and prevents an ArrayIndexOutOfBoundsException.
Edit: Huh? Where did your previous post go? It seems to have disappeared!
