ASAP PLEASE!! It's already passed Deadline. Please response me quick.

***Please read the question carefully***. It's exam.

I have attached the questions and it's supporting code down below with some instructions.

**FastRational.Java is the second screenshot.**

**Please explan the process**

Hints: After reading the slides, you will know you can use three ways to implement the parameter for the setOnAction method: 1)Inner class

2)Anonymous inner class

3)Lamda expression

So if I use the 2, then the code is like:

setOnAction(new EventHandler(){

@override

public void handle(ActionEvent e) {

//get the text from the textfield

// for operand 1 -devide the text into two long value to input into FastRational.

//(FastRational is from assignment 2 and you should copy it to the project and use it)

//do the same thing for operand 2

//get the operator from the textfield

//use the methods from FastRational to calculate the result according to the operator

/ /set the result back to the result textfield } }
