This document provides instructions for an activity to understand variable scope in Java. Learners are asked to create a ScopeDemo class with a main method, declare and initialize three variables of different types within main, and print their values. They should also declare a variable within a code block in main, initialize it, and try printing its value both inside and outside the block to demonstrate that it is not accessible outside its scope of declaration.

1. 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.
