🧮 Java Swing Calculator

This is a Java-based Calculator application built using Swing for the graphical user interface (GUI).
The calculator supports basic arithmetic operations such as addition (+), subtraction (-), multiplication (*), and division (/) along with handling decimal numbers and operator precedence.

The application uses a custom expression evaluation method powered by stacks, ensuring that multi-operator expressions (e.g., 5+2-4*3/2) are computed correctly according to mathematical precedence rules.
