Question

IN CONDITIONAL STATEMENT JAVA,

Outcomes:

 Create a program solution of the given problem applying Java conditional

statements

 Differentiate If, if-else and if-else if-else statements

 Use comparison and logical operators to handle conditional statements in java program.

Instruction:

Read and analyze each problem. Provide a JAVA program to satisfy the required

machine functionality.

Import all java utilities using the syntax: Import java.util.*;

Machine Problem:

Create a java program that would compute and display the total mobile services fee

incurred by a customer. Mobile services include text messages, calls in minutes and

mobile data usage in megabytes.

Each customer was given a customer ID that would indicate the type of mobile plan

he/she availed.

PLAN A

- Customer ID ending

with 0. Loyal member

has 5 digits and above

ID number.

- monthly fixed rate of

P500.00

- allows free text

messaging up to 250

messages. Beyond

that, each message is

charged 90 centavos.

- All-net calls up to 60

mins. Exceeding

minutes applies

P5/min.

- P5/MB. Free use of

mobile data up to

80MB.

- 20% discount from

the total charge for

Loyal member.

PLAN B

- Customer ID ending

with 5. Loyal member

has 5 digits and above

ID number.

- monthly fixed rate of

P750.00

- allows free text

messaging of up to 500

messages. Beyond

that, each message is

charged 70 centavos.

- All-net calls up to 120

mins. Exceeding

minutes applies

P5/min.

- P5/MB. Free use of

mobile data up to

100MB.

- 40% discount from the

total charge.

PLAN C

- Customer ID ending

with 2. Loyal member

has 5 digits and above

ID number.

- monthly fixed rate of

P1,200.00

- allows free text

messaging of up to

1,000 messages.

Beyond that, each

message is charged 50

centavos.

- All-net calls up to 240

mins. Exceeding

minutes applies P5/mins

- P5/MB. Free use of

mobile data up to

500MB.

- 60% discount from the

total charge.

INPUT: The first line of the input file will contain a single integer N that represents the

Customer ID number. Next line consists of 3 integer T, C and D, separated by commas

(,). T is the total number of text messages; C is the total number of calls in minutes and D

is the total data usage in MB.

OUTPUT: The total mobile fee of the customer applying all charges given in the

description and discounts if applicable. In addition, the program must also display an

offer to upgrade the plan type for customers who have exceeded their monthly fixed

rate by 200%. Ex. Plan A – total bill of P1,860.00 means the customer exceeded by

P1,360.00 or 272% from his/her monthly fixed rate of P500 (P1,860-500=1,360).

TEST CASE:

CUSTOMER ID: 39480

300 128 100

----------------------------------------------------

TOTAL ID: P 788.00
