• Install Java version 11 or greater
• Install Intellij Idea community edition - https://treehouse.github.io/installation-guides/windows/intellij-idea-win.html
• Install git on your local machine
• Clone this basic git repository and run a hello world program
• If you can run it, you are set.

Assignment 1

• Once you have learnt it, implement the following with Java
  • Implement a Java application with a main function that can do the following tasks
    • Create a new Product - with product details
      • Name
      • code
      • Category
      • Cost Price
      • Selling Price

      • Store name
      • Store address
      • Store contact number
      • List of products in a store
      • Store should have a function that accepts product code and returns the product object

      • Create function to get price of product by code in a store
      • Create function to get stock value of a product by code in a store

  • Use a json file to import products into your store. All product information should be in a json and this needs to be imported.
  • Use Serializers/Deserializers to do the same. Hint: Use jackson object mapper dependencies to achieve the same
