why does the `android:layout_height="0dp" ` produce the same result as `android:layout_height="wrap_content" ` in XML

Question

XML code----

 <TextView
            android:text="DOGS"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:textSize="24sp" />

XML code----

<TextView
                android:text="DOGS"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textSize="24sp" />

when layout_height set 0dp produces the result which would be prouduce when layout_height set to wrap_content and its same for width as well. if both produces the same then why need the other.
