Autoboxing and Unboxing

In this problem, you will create a program that reads two integer values from standard input, converts them via autoboxing to Integer, converts back via unboxing to int, and displays the results to standard output.

Learning Objective: Understand the mechanism of automatic conversion (autoboxing/unboxing)

Overview

Use Java's automatic type conversion to handle primitives and wrappers transparently.

Input Format

a
b

• Line 1: integer a (subject of autoboxing)
• Line 2: integer b (subject of unboxing)

Specifications

• Autoboxing: automatic conversion int a → Integer
• Unboxing: automatic conversion Integer → int b
• Verify automatic conversion during calculation (receive a + b as int)

Output Format

Autoboxed: a
Unboxed: b
Calculation result: a+b
