Assume that a bool variable is Quadrilateral has been declared, and that an int variable, number Of Sides has been declared and initialized. Write a statement that assigns the value of is Quadrilateral to true if number Of Sides is exactly 4 and false otherwise.

     if (numOfSides==4){

         isQuadrilateral=true;

     }

     else {

         isQuadrilateral = false;

     }

Explanation:

See below a complete program that prompts user to enter number of sides of the triangle

import java.util.Scanner;

public class TestClock {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter the number of sides of the triangle");

       int numOfSides = in.nextInt();

   boolean isQuadrilateral;

    if (numOfSides==4){

         System.out.println("This is Quadrilateral");

         isQuadrilateral=true;

     }

     else {

         System.out.println("This is not Quadrilateral");

         isQuadrilateral = false;

     }

   }

}

answer; certification; plz check first, i believe this is correct. good luck;
