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

Process finished with exit code 0
