15. Object Declaration and Variable Access

We have already defined a class Device with:

• A public integer variable id.
   

Your task is to:

1. Declare a Device object in main().
2. Assign the value 101 to id.
3. Print:
   Device ID: 101

Example

Output:

Device ID: 101

Why this output?

The program assigns 101 to the id variable inside the object and then prints it.

Question Significance

This is the most basic usage of a class: declaring an object and printing one of its variables.
