🔢 Eval-Java 🔢

Python has a function called eval() used to solve mathematical expressions in a string but Java has nothing like this, so i developed this algorithm which can do so.

You can use this package to create a calculator which can solve complex mathematical expressions.

Average Time Complexity: **O(n)**

Average Space Complexity: **O(k + m)**

📝 Sample code

import evaluater.Evaluater;
import evaluater.EvaluaterExceptions;

public class sample {

    public static void main(String[] args)
    {
        try
        {
            
            Evaluater eval = new Evaluater("1280.33/(12*-10.11)");
            System.out.println(eval.evaluate());
        }
        catch(EvaluaterExceptions.InvalidMathExpression excep)
        {
            System.out.println(excep);
        }
    }
    
}

NOTE: evaluate() methods throw InvalidMathExpression exception if the given expression is invalid.
