TR1) Difference between ArrayList and LinkedList?
ArrayList is easy to read data but adding or removing in middle is slow. LinkedList is easy to add or remove data but reading takes more time.
2) Can you overload and override static methods?
We can overload static method by changing parameters. We cannot override static method, it only hides in child class.
3) How does HashMap work internally?
HashMap stores data using a key and finds place using hash value. If two keys go same place, it keeps them together in list.
4) What is the hashCode() contract?
If two objects are equal, their hashCode must be same. If hashCode is same, objects may or may not be equal.
5) What features were introduced in Java 8?
Java 8 introduced lambda to write short code. It also added streams and new date and time features.

Add Elements:
add(E e): Add element to end.
add(int, E): Insert at index.
addAll(Collection<? extends E>): Add collection.
Access Elements:
get(int): Retrieve by index.
indexOf(Object), lastIndexOf(Object): Find element index.
Remove Elements:
remove(int)/remove(Object): Remove by index/element.
clear(): Empty list.
Size & Check Empty:
size(): Count elements.
isEmpty(): Check if empty.
Sublist & Range:
subList(int, int): Get sublist.
addAll(int, Collection<? extends E>): Insert collection at index.
removeAll(Collection<?>): Remove specified elements.
Replace/Set Elements:
set(int, E): Replace element at index.
Iteration:
Loop through elements.
Sort & Reverse:
sort(Comparator<? super E>): Sort with comparator.
Collections.sort(List<T>): Natural order sort.
Collections.reverse(List<?>): Reverse list.
Element Existence:
contains(Object), containsAll(Collection<?>): Check for element(s).
Array Conversion:

__🔥 Java ArrayList Quick Test — Simple Code, Sneaky Logic 😈💻
Don’t underestimate small methods… they love tricking you ⚠️
1️⃣ Output: 2
size() returns the total number of elements
after all add() operations.
2️⃣ Output: true
clear() removes all elements,
so isEmpty() returns true 🧠
3️⃣ Output: 0
indexOf() always returns the first occurrence
of the element, even if duplicates exist 👀
How many did you get right without running the code? 🤔
