Thepurpose of this program will be to provide a simple Binary Calculator.Theuser will enter operands for calculation with the provided “0” and “1” inputJButtons. The operation they want to perform will be selected with a JComboBox.Once the second operand has been entered they may select the “Compute” JButtonand the results of the calculation will be displayed either in Binary orDecimal depending on the state of the JRadioButtons.Theycan then perform another operation using the result as the first operand orpress the “Clear” JButton to start a new calculation.Atotal of two files are DIAGRAM FOR ANDDISCUSSION FOR BinaryCalculatorFrameBinaryCalculatorFrameextends JFrame- JTextField display- JRadioButton binary- JRadioButton decimal- ButtonGroup buttonGroup- JButton zeroButton- JButton oneButton;- JComboBox

>  BinaryCalculatorFrame()Noteson BinaryCalclatorFrameAdditionally,this class will declare two nested classes, one for each type of Event that mayoccur. One will implement ActionListener (for the zeroButton, oneButton,compute, and clear components) and the other will implement ItemListener (foroperator component). The display field does not need a Listener since it willonly be used for output. The binary and decimal radio buttons do not need alistener since their states will only be used by compute when it changes thevalue of the display text field.Data Members:currentOp– represents the operator selected with the following possible values:0– no operator selected1– addition2– subtraction3– multiplication4– divisiondisplayedOperand– int value of the operand that is being displayedoperand1– int value of the first operand in the calculationoperand2– int value of the second operand in the calculationComponent descriptions:display– JTextField, starting text should be “0”, set its width to 20. There is aJTextField constructor that accepts the initial String value and field width asan int. Set it as uneditable and its alignment to right justified like this:display.setHorizontalAlignment(JTextField.RIGHT);binary,decimal – JRadioButtons, initialize binary to true and decimal to false. Addboth to buttonGroupzeroButton– JButton, when pressed will add a 0 digit to the end of displayedOperand andupdate displayoneButton– JButton, when pressed will add a 1 digit to the end of displayedOperand andupdate displayoperator– JComboBox, List of possible operators. List of Strings include, “OP” meaningno operator is selected, and “+”, “-“, “x”, and “/” representing each of thepossible operations. When the selection of the box is changed (if it has notbeen changed to 0) updates currentOp to the correct value depending on theoperator selected. The current value of the displayed operand should be storedinto operand1 and the displayed operand cleared out (set to 0) and updated inthe display.compute– JButton, when pressed the user wants to perform the selected operation (ifany). The currently displayed operand will be the second operand in thecalculation. Based upon the currently selected operation calculates the resultand sets this as the current value of displayedOperand. Depending on whichradio button is selected (either binary or decimal) the result will bedisplayed in the corresponding base. The currently selected operator will bereset to “OP”/0.Youdo not need to write methods to do calculations with binary values. Instead,convert the operands into decimal and perform the calculations on the decimalvalues.Thefollowing static Integer methods will be extremely helpful:StringtoString(int) – takes an int and returns a String representationintparseInt(String) – takes a String and converts it into an intintparseInt(String, int) – takes a String and a base (such as base 2 for binary).Converts the String in the provided base and returns its decimal value as anintStringtoBinaryString(int) – takes a decimal value and returns its binaryrepresentation as a Stringclear– JButton, resets all values. displayedOperand, operand1, operand2, andcurrentOp to 0, displayed text to “0”, and selected Operator to “OP”.Other Notes:Import all of the necessaryclassesName the components asshow in the examplePlease make sure yourprogram compiles with just the two source code files and command: “javac”.An IDE may add extra stuff to your source code and causes it to need extraconfigurations to compile.Examples:
