If you ran <xref ref="java-full-fraction-class" text="type-global"/>, you probably noticed that the output is not very satisfying. Chances are your output looked something like <xref ref="java-no-friendly-output" text="type-global"/>.

<p>
The reason is that we have not yet provided a friendly string representation for our <c>Fraction</c> objects.
Just like in Python, whenever an object is printed by the <c>println</c> method it must be converted to string format.
In Python you can control how that looks by writing an <c>__str__</c> method for your class.
If you do not then you will get the default, which looks something like <xref ref="java-no-friendly-output" text="type-global"/>. We will see how to provide a friendly string representation for our <c>Fraction</c> class in <xref ref="inheritance" text="type-global"/>.
