$(1)$ Switch To Light Mode

$($HAS TWO parts$/$methods$)$

Question $1(75$ points $)$

Decision or Selection Structures and Loops

$($Decision Tree: If $-$ else if $-$ else loop$)$ The charges for Wireless

for one of the mobile companies is given in the following table.

Use if else if else decision structure.

Write a JAVA method to calculate the annual charges fine

calcAnnChargeFirstname called from main.

The variables in the program should be named as shown below

and should be input by the user:

expectedDataUsage firstname$\_//($Expected data usage per user

in the household $-$ int data type$)$

numUsers firstname $//($Number of users in the household $-$ int

Data type$)$

tax$\_$pct$\_$firstname $//($ A double data type$)$ This is the tax

percentage on the invoice. Tax is applied on the overall

calculated charges.

The program also should display the following message for each

of the above cases as shown in the table below:

Allowed Data Per User

Less than $15GB$

Less than $25GB$

Less than $50GB$

Your method should calculate the Annual total charges per

household including the taxes and also should do the display.

Charges should be calculated using an if $-$ else if $-$ else

decision structure and make it more efficient by not repeating

code as much as possible.

The Message from the above table should be displayed using a

Switch $-$ Case decision structure.

$($Following are examples which you can use for testing. Please
