Java GUI (Calculator) Program

Create a program for Integral Calculator Indicate "Integral Calculator\" on the title bar. The result of value is always empty. The program will ask the user to enter a function and the "=\" or enter key will display the result that always have "+ C\" at the end (see sample output below). The "DEL\" will act as a backspace and the \"CLR\" will clear the text area from any previous inputs. Add functionality on the close button. Provide the necessary method and appropriate exception handling needed in the calculator program. The calculator should support the following: Integral Calculator .- unnnum HIE-En "III- Ill-EH \"I...\" Please use the given functions below for testing the functionality of the integral calculator program. The answers are provided as a reference for output: Findxo) 1. f(x)=x+e2x=ezxz+x2+c 2. f(x)=ln(x+1)=(x+1)ln(x+1)x+C 3. f (x) = c053x = \"23x + C
