How To Create Calculator Using Java by naijatechguide: 9:29pm On Dec 15, 2020
Using Java to create calculator is easy to do and I will tell you guys how to Use the Addition Button while creating a Calculator.
Step 1: Let’s first of all declare and initiate a variable that will come in handy for us. double total=0.0; // created as an instance variable. I meant inside a class.

Step 2: In the addButton method, get data from the displayBox and add it to total. For example: total = total + Double.parseDouble (displayBox.getText()); Double.parseDouble() method was used to pass whatever we are getting as double to the total variable initially declared as double.

Step 3: Clear the displayBox e.g displayBox.setText(""wink;
