Answer:
import java.util.Scanner;
public class Polygon {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Type the number of sides:");
int sides = sc.nextInt();
System.out.println("Type a side length:");
double length = sc.nextDouble();
if (sides== 5){
System.out.println("Pentagon, length "+length);
} else if (sides == 6){
System.out.println("Hexagon, length "+length);
} else if (sides == 7){
System.out.println("Heptagon length "+length);
} else if (sides == 8){
System.out.println("Octagon, length "+length);
} else if (sides == 9){
System.out.println("Nonagon, length "+length);
} else if (sides == 10){
System.out.println("Decagon, length "+length);
} else if (sides == 11){
System.out.println("Undecagon, length "+length);
} else if (sides == 12){
System.out.println("Dodecagon, length "+length);
} else {
System.out.println("Please choose a valid number.");
}
}
}
Explanation:
The Java source code defines a class called 'Polygon' the main method of the class prompts for user inputs for the sides and length variables. The nested if-statement prints the type of polygon with respect to the number of sides.
