✅ Operations on ArrayList
✅ Size of ArrayList
✅ Reverse printing
✅ Sorting ArrayList

Day 29 of learning java ☕:
Today I learnt more on Data structures starting with Arraylist.
In Java, arrays give you fixed-size storage.
Array lists give you flexibility.
When to use:
•Use arrays when the size is known.
•Use ArrayLists when data keeps changing.

Day 28 of learning java ☕:
Today I learnt about Another different way to take user input apart from using scanner which is buffered reader,
BufferedReader in Java is built for speed.
Instead of reading data one character at a time, it reads chunks into memory, making file

The post is misleading, but I misread it completely.
Like Java ArrayLists, Python lists contain pointers, not primitive values. In Java this is an actual allocated object (the Integer class), not just a pointer. So it consumes more memory too.

Just cracked a classic HackerRank problem ⚡
👉 Build a list of ArrayLists
👉 Answer queries
👉 Print the value or “ERROR!”
The trick?
✔️ Zero-based indexing
✔️ Clean input handling
✔️ Try–catch = lifesaver
Building in public. One problem a day.

You're thinking about it wrong, I think ArrayLists are implemented with linked lists.

✨ DSA Journey - Day 91
I thought I understood ArrayLists… until this question humbled me.
At first glance, it looked simple.
Just build an array, right?
But the moment I started solving it…
my brain just froze.

✨ DSA Journey - Day 88
Today I practiced ArrayList in Java with several concepts:
• Iteration and reverse traversal
• Finding max element
• Swapping elements
• Sorting (ascending & descending)
• 2D ArrayLists
• Container With Most Water (brute force & two-pointer)

☕ Java: Snuck in a quick session on ArrayLists during my college break.
Mastered dynamic resizing and searching using methods like add(), indexOf(), and set().
Collections are making data manipulation so much smoother! 💻🔥

print true
the type parameters (like String and Integer) are erased at runtime, so both lists are just ArrayLists, making their classes equal.
