In java Create a GUI application for a calculator that can perform logcal operations such as And, Or, Xor, Not, Shift Left, and Shift Right. The calculator includes buttons 0 to 9, plus buttons labeled A, B, C, D, E, and F for entering a number in hexadecimal format. The user can select the input number radix from Binary, Decimal, or Hexadecimal from three radio buttons. If the Binary radio button is selected, only buttons 0 and 1 should be enabled and all the others should be disabled. if the Decimal radio button is selected, buttons labeled A, B, C, D, E, and F should be disabled. Check the following sample layout of the project (check the Microsoft Calculator application in programmer mode for more details)
