Task $3$: Array of Objects

$1.$ Task Description: Briefly explain the task, which involves creating an array of objects and modifying object properties through array references.

$2.$ Code Implementation: Include the code that creates an array of Point objects and modifies their properties. Example:

java

$```$

Point$[]$ points $=$ new Point$[3]$;

points$[0]=$ new Point$(10,20)$;

points$[0].$setX$(3)$; $//$ Modify the x$-$coordinate

$```$

$3.$ Explanation: Explain the process of creating and modifying objects inside an array. Highlight how arrays of objects differ from arrays of primitive data types.

$4.$ Output: Provide the output before and after modifying the object properties. Example: Before modification: $[$Point$[$x$=10,$ y$=20],$ null, null$].$ After modification: x$=3.$

Part $3$: Reflection and Discussion

Key Takeaways: Summarize the key concepts you learned from completing the lab $($e$.$g$.,$ array manipulation, object handling, aliasing$).$

Note: You are free to express yourself in this part. You can summarize the key knowledge points of the two courses and labs. Just briefly summarize each point you raise.
