Java GUI Calculator
In this homework, I am working on Java GUI Components and interfaces. The objectives of this program are to learn the use of Java swing components, GroupLayout, ActionListener, and MouseListener interfaces. The calculator must come with a menu (which its requirements are shown in the image below) and it must be capable of accepting hex, dec, oct, and bin inputs. It must be graphically similar (while not necessarily 100% so) to the image shown below, and be capable of using all of its buttons.
All of the test cases that will come with this calculator are...
Disable Dword, Word, Byte, but keep the buttons there. Also, no interaction of the mouse on the binary bits area is required. Just display 64 bits for allthe items with appropriate bits filled in based on the value in the number field. View Edit Help Menu items View Hide and Show the calculator Edit Copy the Text Help Perform the same as the actual Windows calculator 0000 0000 0000 0000 0000 0000 0000 0000 0000 31 Quot Mod A OHex Dec C 7 8 9 OBin Qword ODword E 1 2 3 Word OByteSolution
