Question

Assume that a variable variable, number Of Sides has been initialized. Write a statement that assigns the value True to the variable is Quadrilateral if number Of Sides is exactly 4 and False otherwise.

Answer 1

Answer:

public class ANot {

   public static void main(String[] args) {

   

       int numberOfSides = 20;

       boolean isQuadrilateral;

       if(numberOfSides==4){

           isQuadrilateral = true;

           System.out.println("The triangle is quadrilateral");

       }

       else{

           isQuadrilateral=false;

           System.out.println("The triangle is not quadrilateral");

       }          

}

}

Explanation:

1. Create and Initilize the int  variable numberOfSides (You can also receive this from a user using the scanner class for example).
2. create a boolean variable isQuadrilateral
3. Use if and else statement to check if numberOfSides ==4 and assign true to isQuadrilateral else assign false
