To make the red fishes 98%, 50 fishes have to be removed from the aquarium.
Calculate 1% of 200 fishes, which is 2 fishes.
To make the red fishes 98%, subtract 1% (2 fishes) from 99% (198 fishes).
To find the number of fishes to be removed, divide the difference by 1% (2 fishes).
Therefore, 50 fishes have to be removed to make the red fishes 98%.

To make the red fishes 98%, 50 fishes have to be removed from the aquarium.
Calculate 1% of 200 fishes to find the number of red fishes.
Subtract the number of red fishes from 200 to find the number of non-red fishes.
Calculate 2% of the total number of fishes to find the desired number of red fishes.
Subtract the desired number of red fishes from the current number of red fishes to find the number of fishes to be removed.

To make the red fishes 98%, 50 fishes have to be removed from the aquarium.
Calculate 1% of 200 fishes to find out how many fishes represent 1%.
Multiply the result by 2 to find out how many fishes represent 2%.
Subtract the result from 200 to find out how many fishes represent 98%.

An ArrayList is a dynamic array in Java that can grow or shrink in size during runtime.
ArrayList is a class in Java's Collection framework.
It implements the List interface and allows duplicate elements.
Elements can be added or removed using methods like add(), remove(), etc.
It can also be sorted using the sort() method.
Example: ArrayList
names.add("John"); names.add("Mary"); names.remove(0);
ArrayList is a resizable array while LinkedList is a doubly linked list.
ArrayList is faster for accessing elements while LinkedList is faster for adding or removing elements.
ArrayList uses contiguous memory while LinkedList uses non-contiguous memory.
ArrayList is better for random access while LinkedList is better for sequential access.
Example: ArrayList - List
Java is not a pure OO language due to primitive types not being objects.
Primitive types like int, boolean, etc. are not objects in Java
They do not have methods or inheritance like objects do
This violates the principle of everything being an object in pure OO languages
Wrapper classes like Integer, Boolean, etc. were introduced to provide object-like behavior for primitives
Object-oriented languages support inheritance and polymorphism, while object-based languages do not.
Object-oriented languages allow for the creation of classes and objects, and support inheritance and polymorphism.
Object-based languages only support objects, but do not have the concept of classes or inheritance.
Examples of object-oriented languages include Java, C++, and Python, while JavaScript is an example of an obj
Inheritance is a way to create new classes based on existing ones. Abstraction is a way to hide implementation details.

Abstraction allows a class to provide a simplified interface to its users while hiding its implementation details.
