I am getting this type of error while compiling java code: error: non-static variable sc cannot be referenced from a static context

Following is my code (Quite Simple)

import java. util. Scanner;
class OOP {

Scanner sc=new Scanner(System. in);

public static void main(String[] args){

System. out. println("Define OOP: ");
String oopdefinition = sc. nextLine();

}

}

None. the wood chuck riddle says if he could chuck wood so the answers none

For question 1, i'm a bit stuck between serif fonts or large enough type to read. serif fonts are good fonts to use because their easy to read. but you also need your type be large enough to read. if i had to say what you need to consider most important, i would say d is the answer.  for question 3, i believe the answer is d. it seems most appropriate to do that. on every page or every other page would be too much, and only on the contact page just seems inappropriate.  for question 4, it's probably a. by "color scheme" it doesn't mean just one color, but a set of colors. colors that are complimentary to each other. having too many is too distracting so it's best to limit it as much as possible, but not to the point where your website looks dull.hope this !
