- Simple Calculator built with Eclipse window builder



  



- After optimizing the app, updated image is as following:



  



- Made some UI changes, result as following: 



  



## [Implementation](https://github.com/af4092/Mini-Calculator/blob/main/Mini_Calculator/src/com/Login/OptimizationUI.java)

- `Java Swing` application for a mini calculator. It creates a `GUI window` with various buttons and a text field to perform basic arithmetic calculations.

- Here's a breakdown of the code:

  - The class `Optimization` extends `JFrame` to create the main frame for the calculator.

  - The constructor sets up the frame by setting its size, title, and default close operation.

  - The `contentPane` panel is created and set as the content pane for the frame.

  - Various Swing components such as buttons, labels, and text fields are created and added to the content pane.

  - Action listeners are added to the buttons to perform specific operations when clicked.

  - The `btnPlus`, `btnMinus`, `btnMultiply`, `btnDivide`, and `btnSquare_1` buttons set the `operation` variable to the respective operation symbol (`+`, `-`, `*`, `/`, `xy`).

  - The `btnEqual` button calculates the result based on the selected operation and displays it in the text field (`tfNumber`) and a label (`lbCalculation`).

  - Other buttons (`btnSqrt`, `btnSquare`, `btnClear`, `btnOne`, `btnTwo`, ..., `btnNine`, `btnZero`) handle specific actions such as square root, square, clearing the text field, and entering numeric values.

  - The `Optimization` class represents the main window of the calculator application.

- To run this code, we need to have the necessary dependencies for Java Swing and compile and execute the code using a Java development environment.
