Contrast is important when designing a web page for many reasons. One of the most important reasons is because if you don't have contrast, you won't be able to read what is written on the page. Your eyes will have to strain really hard or it just simply won't be possible to read at all. Another really important reason is that contrast makes the web page look visually appealing. Whereas, if you don't have contrast it is all kind of jumbled together. As you can see there is a plethora of reasons contrast is important.
I hope that helps u!!

Two concepts central to JavaFX are a stage and a scene.
Answer:
Assuming that TV was working fine and it stopped working when you restart or after power shutdown. Flat Black or blue screen or snow are all seems to be having HDMI cable sync issues. It can be fixed based on the model of the TV and connectivity it is using.
I would suggest to start with very basic step and should go step by step unless we narrow down the problem.
- Turn off all the components, unplug the cables and plug them back by leaving HDMI cables intact. So this process will reset all the units and may help in renegotiation.
- Plug all the cables and Turn on the TV. Plug all other components like sound receiver and source device and Turn on the power. This may solve the problem.
- If issue still persist. Unplug and Plug back HDMI cables and surrounding components in HDMI path. It may solve the issue.
- If the issue still persists, then change the HDMI cable itself and try rebooting all components.
- If input is changed then it might have caused the issue. So identify the cable from the receiver to the TV. figure out its input and change the TV input to that value and it will work.
- In some TV's if power reset happens, It may revert to TV mode then change the video input based on your TV model.
- If the receiver is connected to TV via Coax then change the channel as per TV guide.
- If the receiver and its component is using AV or HDMI then use TV remote to change the input source until correct feed is found.
- If issue still persist, check the cable with another TV and see if it works. If its not then cable is at fault.
- If the cable is fine then change the TV and try above steps.If it works then TV is at fault.

Explanation:
Following are the difference between overriding and overloading
(1) Method overloading means method having same name but different parameter or method signature Whereas Method overriding means method having same name and same parameter or signature.
(2) Method overloading is achieved the compile time Polymorphism whereas Method overriding is achieved the Run time Polymorphism .
(3 ) In method overriding child class have facility to provide a specific implementation of a method which is already defined by parent class method whereas there is no such facility is available in method overloading
(4 )Programming structure of method overloading
class test
{
void fun()
{
// statement
}
void fun(int b)
{
// statement
}
}
In this fun() method name is same but different signature I.e void fun() and void fun(int a);
Programming structure of method overriding
class parent
{
void fun()
{
// statement in parent class
}
}
class child extends test
{
void fun()
{
// override the statement in child class
}
}
In this fun() method have same name and same signature in both class
Answer:
The audience development technique that best describe the process Nicolal wants to implement is;
C Pull technology
Explanation:
Pull technology is a form of network mode of communication in which the initial data request comes from the client side of the network for it to be handled by the server side of the network.
Given that Nicola wants a demand-based content to his website for customers to access information when they wish to, the process is similar t the podcasting in which each new content is posted to a specific RSS feed from where it can be requested by a mobile app, directory or a RSS feed reader
The counter technology is a push technology where the servers push content to intended clients, such as for an incoming call, instant messaging, synchronous conferencing (online c h a t) and files.
