+## Getting Started
+
+Welcome to the VS Code Java world. Here is a guideline to help you get started to write Java code in Visual Studio Code.
+
+## Folder Structure
+
+The workspace contains two folders by default, where:
+
+- `src`: the folder to maintain sources
+- `lib`: the folder to maintain dependencies
+
+Meanwhile, the compiled output files will be generated in the `bin` folder by default.
+
+> If you want to customize the folder structure, open `.vscode/settings.json` and update the related settings there.
+
+## Dependency Management
+
+The `JAVA PROJECTS` view allows you to manage your dependencies. More details can be found [here](https://github.com/microsoft/vscode-java-dependency#manage-dependencies).

+/*
+Write a Java program that repeatedly accepts two integers from the keyboard and prints the quotient to
+the console. Your code must adhere to the follow specifications:
+ - The user must enter 0 for both the numerator and denominator to exit the program.
+ - You must read the input values using the Scanner’s next() method and then convert to a primitive integer using Integer.parseInt. 
+   In case of an exception (when converting the string to an integer), the program must (1) print the corresponding stack trace (printStackTrace) 
+   and (2) reset the Scanner object.
+ - The program must catch division by zero exceptions and print a corresponding message in case
+   one occurs. The error should not be printed if the user intends to exit.
