In this activity, you will write a Java program to understand the scope of variables in Java. Follow the instructions below: 1. Create a new Java class called "ScopeDemo" and define a main method. 2. Inside the main method, declare and initialize three variables of different data types (e.g., int, double, String) with different names. 3. Print the values of these variables to the console. 4. Declare a new variable inside a block of code (e.g., an if statement or a for loop) within the main method. Initialize this variable with a value. 5. Try to access this variable outside of the block of code in which it was declared. 6. Print the value of the variable both inside and outside the block of code. Use the editor to format your answer Question 2 public class Student { private int id; private BirthDate birthDate; public Student (int son, int year, int month, int day) { id = ssn; birthDate new BirthDate(year, month, day); } public int getId() { return id; } public BirthDate getBirthDate() { return birthDate; } public class BirthDate { private int year; private int month; private int day; public BirthDate(int newYear, int newMonth, int newDay) { year newYear; month newMonth; day newDay; } public void set Year (int newYear) { year newYear; } } Question 1 The Student class above is immutable A True B) False 0 Points In this activity, you will write a Java program to understand the scope of variables in Java.
