Answer:
See code and explanation below.
Explanation:
Assuming this complete problem: "Shipping Charges The Fast Freight Shipping Company charges the following rates: Weight of Package Rate per 500 Miles Shipped 2 pounds or less $1.10 Over 2 pounds but not more than 6 pounds $2.20 Over 6 pounds but not more than 10 pounds $3.70 Over 10 pounds $3.80 The shipping charges per 500 miles are not prorated. For example, if a 2-pound package is shipped 550 miles, the charges would be $2.20. Write a program that asks the user to enter the weight of a package and then displays the shipping charges. "
For this case we can create the following Java code:
// Java Scanner to take regular expressions
import java.util.Scanner;
// Definition of the variables
class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
//INPUT S : we define the weigth and the charge based on the weigth
double pound, shipCharge, total;
final double weightCharge1=1.10, weightCharge2=2.20, weightCharge3=3.70, weightCharge4=3.80;
//OUTPUT S: We ask for the weigth and would be stored on pound variable
// We define the if conidtion based on the restrictions given
System.out.print("Enter the package weight(lbs):");
pound=input.nextDouble();
//Complete the remain conditions
if(pound>=0.01 && pound<=2){
shipCharge=pound*weightCharge1;
}
else if(pound>=2.01 && pound<=6){
shipCharge=pound*weightCharge2;
}
else if(pound>=6.01 && pound<=10){
shipCharge=pound*weightCharge3;
}
else if(pound>=10.01){
shipCharge=pound*weightCharge4;
}
else{
shipCharge=-1;
}
//OUTPUT: We print the final solution and if we have an error we ask for other value for the input
System.out.println();
if(shipCharge!=-1){
total=shipCharge;
System.out.printf("The Weight is: %,.2f lbs\n",pound);
System.out.printf("The total Shipping Charge: $%,.2f\n",total);
}
// Invalid case
else
System.out.println("Invalid input, must enter a value higher than 0.01");
}
}
