A Java programmer has developed a GUI with several different fields for inputting values and indicating choices via buttons, all using JavaFX. To manage the user experience, the programmer wishes to have the field of input automatically advance to the next input field or button after an entry is made. To do this, the programmer should use the

EventHandler

Explanation:

In order to do this the programmer needs to use the EventHandler class. This class allows the computer to listen for certain user actions such as pressing a button. Using this on a button would then allow the programmer to specify what they want to happen when the user clicks the button or performs a certain action. For example, in this scenario, the programmer would program an EventHandler so that when the button is clicked it saves the input to a variable and changes the input field to the next option.

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
