build a Java GUI on eclipse using javafx while being assisted by the Scene Builder . The task is to create a simple calculator that can add, subtract, multiply, and divide two numbers. You do not have to worry about compound statements like adding, subtracting, multiplying and dividing in one operation. The calculator can be simple and all you have to do is worry about one operation (adding, subtracting, dividing, or multiplying) at any point in time and only two numbers. For you to be successful you need buttons representing the number 0 all the way up to the number 9. You also require and add button, a subtract button, a multiplication button, and a division button. Lastly, you require an equals button. When the equals button is pressed, you need to have some kind of output you can use a any element that will allow you to that, or simply paint on the panel.
