🔹 Scanner
This is the class name from Java’s standard library (java.util.Scanner) that helps you read input (like from keyboard, files, etc.).
🔹 sc
This is the name of the variable (you can name it anything, like input, reader, etc.).
Here, sc is just a short name we’re using to represent the Scanner object.
🔹 =
This is the assignment operator. It assigns the object on the right-hand side to the variable on the left-hand side.
🔹 new
This is a keyword in Java that is used to create a new object (in this case, a new Scanner object).
🔹 new Scanner(...)
This part creates a new instance (object) of the Scanner class.
🔹 System.in
This is a built-in input stream that refers to the keyboard input (standard input).
System is a predefined class, and in is a static field of type InputStream.
