Admission task
Description of admission task "Calculator"
Create a console application "Calculator". The application must read the arithmetic operations entered by the user from the console and output the result of their execution to the console.
User inputs the whole mathematical expression in ONE line. Solutions that prompt the user to enter digits and operations one by one are NOT eligible.
Create a console application "Calculator". The application must read the arithmetic operations entered by the user from the console and output the result of their execution to the console.
User inputs the whole mathematical expression in ONE line. Solutions that prompt the user to enter digits and operations one by one are NOT eligible.
Requirements
- The calculator can perform addition, subtraction, multiplication and division operations with THREE numbers: a + b - c, a - b + c, a * b - c, a / b * c.
- Two numbers can also be used as input.
- The calculator must accept input numbers from 1 to 10 inclusive, no more. At the output, the numbers are not limited in size.
- The calculator can only work with integers.
- When the user enters invalid numbers, the application throws an exception and exits.
- When the user enters a string that does not match one of the above arithmetic operations, the application throws an exception and exits.
Input:
5 - 2 + 8
Output:
11
Input:
5 + 8 - 2
Output:
11
Input:
-5 + 8 * 2
Output:
11
Evaluation criteria
Pay attention to the principles of OOP, try to break the program into logical classes. Solutions in which all the program code is in one class will be underestimated. Demonstrate your skill in working with different syntactic constructions, do not forget about exceptional situations in which the program cannot be executed due to incorrect input data.

Struggling? We've got you covered!
We offer a free crash course to get you started in Java from scratch.
Help Section
- Start by installing the JDK from the ORACLE website - download. You can choose any version, but we recommend you 8 or 11. To download, you need to register on the ORACLE website - it will not take much time.
2. These materials will help you install and configure the JDK:
3. Install a development environment (we recommend IntelliJ IDEA)
- If you are not familiar with Git and Github you should familiarize yourself with this article
- https://www.youtube.com/watch?v=USjZcfj8yxE
- https://www.youtube.com/watch?v=mf2-MOl0VXY
Side-by-side code snippets - comparison of code examples in different languages. You can choose your language and Java to study similarities / differences.
Advises:
Useful video about debugging in Intellij Idea
- If you don't understand English, use a dictionary/translator.
- Feel free to google the text of the error.
- If a large piece of code does not work, try debugging a small part of it.

If this is the first program you are trying to write - try to practice the basics on simpler problems (see resources above).
Try to break a large task into small subtasks and solve them separately - it's much easier. Or simplify the problem to a variant that you can solve, and then refine it to the specified requirements.
