Java Console Calculator (Maven)

This project is a simple console-based calculator implemented in Java, mirroring the behavior of the JavaScript calc-formula.js version.

It is intended to live at:

• https://github.com/arkenidar/java-console-calculator

Supported features (kept in sync with JS):

• Operators: +, -, *, /, ^
• Parentheses: (, )
• Decimal numbers (e.g. -0.5, 5/2)

The core logic lives in Calculator.calculate(String) in src/main/java/com/example/calculator/Calculator.java.

Build and Run with Maven

Prerequisites:

• JDK installed
• Maven installed (mvn -v works)

From the project root:

cd /home/arkenidar/temporary/java-console-calculator
mvn -q clean compile
mvn -q -DskipTests exec:java

This will run com.example.calculator.Calculator.main, which executes a small test suite (same tests as in calc-formula.js) and prints whether each one is true.

Keeping JS and Java in Sync

• JS reference repo: https://github.com/arkenidar/calculator-raw
  • File: calc-formula.js (calculate(formula) and tests at the top).
• Java port repo: https://github.com/arkenidar/java-console-calculator
  • File: src/main/java/com/example/calculator/Calculator.java.

When you add a new test or operator in JS:

• Update the Java calculate method in the same way.
• Add the corresponding test line in Calculator.main.
