Java code to create a calculator to perform the four basic arithmetic operations (addition, subtraction, multiplication, and division).
- The application is developed using the Eclipse IDE.
- To use the application you need to run the MainApp.java class
- You would be prompted to enter an arithmetic expression as the input.
- The input is then validated. In case you have entered an invalid input, the same would be displayed.
- If the input is valid, you would see the result or the numerical value obtained after evaluating the arithmetic expression.
