provide in Java Programming: ShippingCharges Class The Fast Freight Shipping Company charges the following rates: Weight of Package (in kilograms) Rate per 500 Miles Shipped 2 kg or less $1.10 Over 2 kg but not more than 6 kg $2.20 Over 6 kg but not more than 10 kg $3.70 Over 10 kg $4.80 The shipping charges per 500 miles are not prorated.

For example, if a 2 kg package is shipped 550 miles, the charges would be $2.20. Design a class that stores the weight of a package, and has a method that returns the shipping charges.

complete with this files :

ShippingCharges.java class ShippingCharges { public static final double RATE_UNDER_2KGS = 1.1; public static final double RATE_UNDER_6KGS = 2.2; public static final double RATE_UNDER_10KGS = 3.7; public static final double RATE_OVER_10KGS = 4.8;

private void go() {

// Input weight double weight = 0.0; double shippingCharges = computeShippingCharges(weight); System.out.printf("$%.2f Shipping Charges for %.2f KGs", shippingCharges, weight); }

double computeShippingCharges(double weight) { // logic to determine shipping charges using constants above return 0.00; }

public static void main(String[] args) { new ShippingCharges().go(); } }
