Sum of Integers Using Autoboxing and Unboxing

Objective

This Java program demonstrates the use of autoboxing and unboxing to calculate the sum of a list of integers. It also shows how to parse string inputs into integer values using Integer.parseInt().

Key Concepts Demonstrated

• Autoboxing: Automatically converting primitive int values into Integer objects
• Unboxing: Converting Integer objects back to primitive int
• String Parsing: Using Integer.parseInt() to convert user input from strings to integers

How to Run

1. Compile the program: javac IntegerSumCalculator.java
2. Run the program: java IntegerSumCalculator
3. Enter integers separated by spaces when prompted
4. The program will display the sum of all valid integers entered
