Can you give the java code for both the questions? /sraja/AppData/Local/Temp/PROG241 78%20 %20Final%20Exam%20 %20Fall%20201 7%20%20A.pdf Section 2- GUI Applications 4) Create the following GUI and provide full functionality for the calculator Calculator- 5) Write a temperature conversion application that converts from Fahrenheit to Celsius. The Fahrenheit temperature should be entered from the keyboard (viaa JTextField). A JLabel should be used to display the converted temperature. Use the following formula for the conversion: Celcius (Farenheit-32) 010 acer
