Lab 5 – Java Sequences
Assignment needs to be done in IntelliJ IDEA with SDK.
Create a Java program that prompts a user to input the radius of a circle and computes the circle’s area and perimeter.
Start your program as follows:
package edu.cscc;
import java.util.Scanner;
// TODO add comments with your name and the purpose of the program
public class Main {
private static Scanner input = new Scanner(System.in);
public static void main(String[] args) {
double radius, area, perimeter;
// TODO your code goes here
}
}
Example Output
Circle program
Enter the radius of your circle: 3
The area of a circle with a radius of 3.0 is 28.274333882308138
The perimeter of a circle with a radius of 3.0 is 18.84955592153876

Lab 6 – Java Decisions
Assignment same program....but needs to be in a different file
Create a Java program that prompts a user for the cost of a product and then prompts the user for one of three shipping options
- Standard shipping (enter ‘1’) for $7.95
- Express shipping (enter ‘2’) for $13.95
- Priority shipping (enter ‘3’) for $23.95
The program then prints the cost of the product, the cost of shipping, and the total cost.
Start your program as follows:
package edu.cscc;
import java.util.Scanner;
// TODO add comments with your name and the purpose of the program
public class Main {
private static Scanner input = new Scanner(System.in);
public static void main(String[] args) {
int shippingType;
double shippingCost, productCost, totalCost;
// TODO your code goes here
}
}
Example Output
Shipping costs
Enter the cost of the product ordered: 157.90
Standard shipping (enter ‘1’) for $7.95
Express shipping (enter ‘2’) for $13.95
Priority shipping (enter ‘3’) for $23.95
Enter your choice (1, 2 or 3): 2
The cost of the product is 157.9 plus shipping of 13.95 equals 171.85
