BAHAGIA B: KAJIA KES (30 MARKAH)

SECTIO B: CASE STUDY (30 MARKS)

Arahan: Baca kajian kes di bawah dan jawab semua soalan-soalan berikut.

Instruction: Read the case study below and answer all following questions.

Bank Satu Malaysia memerlukan anda menulis satu aturcara bagi membantu pegawai di

bahagian pinjaman untuk meluluskan permohonan pinjaman peribadi. Aturcara ini

meminta pengguna memasukkan data pemohon iaitu pendapatan tahunan, tempoh tahun

pinjaman, jumlah pinjaman dan status pelanggan. Status pelanggan adalah 0 jika

pemohon adalah pelanggan biasa manakala status pelanggan adalah 1 bagi pelanggan

terpilih. Permohonan diluluskan jika nilai jumlah pinjaman dibahagi dengan tempoh

adalah kurang atau sama dengan pendapatan pemohon dibahagi dengan 12. Di samping

itu, permohonan juga diluluskan jika pemohon berstatus pelanggan terpilih dan nilai

jumlah pinjamannya dibahagi dengan tempoh adalah kurang atau sama dengan

pendapatannya dibahagi dengan 10. Untuk kes yang lain permohonan adalah ditolak.

Aturcara ini hendaklah memaparkan mesej ringkas memaklumkan pengguna tentangkeputusan permohonan. Kod pseudo untuk menentukan keputusan permohonan

pinjaman adalah seperti berikut:

The One Malaysia Bank wants you to write a program to help its loan officers approve personal loan applications. The program should prompt the user for the applicants

yearly income, loan duration in years, amount of the loan and customer status. Thecustomer status is either 0 for a regular customer or 1 for preferred customer. Loan is

approved if the loan amount divided by the duration is less than or equal to theapplicants income divided by 12. Also, approve the loan if the customer is a preferred

customer and the amount of the loan divided by the duration is less than or equal to the

applicants income divided by 10. In any other case, reject the application. The programshould display a simple message informing the user of its decision. The pseudo code to

decide the loan application is as follows:

Aturcara ini mestilah boleh memproses sebanyak manapun permohonan pinjaman. Jika

pengguna memilih untuk berhenti memproses permohonan, aturcara ini hendaklah

memaparkan jumlah pinjaman yang telah diluluskan dan jumlah pinjaman yang telah

ditolak.

The program must be able to process any number of loan applications. When the user

decides not to process more applications, the program should display the total number ofapplications approves and the total number of applications rejected.

if (amount / duration)

Berikut adalah contoh output bagi program tersebut:

Following is the sample output of the program:

Di dalam aturcara ini, 2 kelas akan ditakrifkan: kelas Loan dan kelas

LoanApplication. Kelas Loan adalah digunakan untuk tujuan membuat keputusan

tentang permohonan pinjaman. Ia hanya mempunyai satu kelakuan statik bernama

decideLoan() yang mempunyai 4 parameter formal iaitu pendapatan tahunan, tempoh

pinjaman, jumlah pinjaman dan status pelanggan. Kelakuan ini akan mengembalikan

nilai true jika pinjaman diluluskan atau falsejika pinjaman ditolak (berdasarkan kodpseudo yang telah diberikan di atas).

Kelas LoanApplication pula adalah aturcara utama yang mempunyai kelakuan

main() yang akan mendapatkan data dari pengguna, memproses pinjaman denganmemanggil kelakuan decideLoan() dari kelas Loan dan memaparkan keputusan.

Do you want to process a customer?Enter 1 for Yes, 0 for No: 1

Enter income: 24000.00Enter duration in years: 4Enter amount of loan: 5000.00Enter customer status (0- regular, 1 preferred): 0The loan is approved.

Do you want to process a customer?Enter 1 for Yes, 0 for No: 1Enter income: 24000.00Enter duration in years: 4Enter amount of loan: 10000.00Enter customer status (0- regular, 1 preferred): 0

The loan is rejected.

Do you want to process a customer?Enter 1 for Yes, 0 for No: 1Enter income: 24000.00Enter duration in years: 4Enter amount of loan: 10000.00Enter customer status (0- regular, 1 preferred): 1The loan is rejected.


Enter income: 24000.00Enter duration in years: 5Enter amount of loan: 10000.00Enter customer status (0- regular, 1 preferred): 1The loan is approved.


Number of loan approved: 2Number of loan rejected: 2

Semua langkah ini akan diulang sehinggalah pengguna memilih untuk berhenti yang akan

menyebabkan bilangan permohonan yang diluluskan dan yang ditolak dipaparkan

sebelum aturcara tamat.

In this program, 2 classes will be defined: Loanclass andLoanApplication class.

Loan class is used to decide the result of a loan application. It has only one static methodnameddecideLoan()which has 4 formal parameters: yearly income, loan duration,

loan amount and customer status. This method returns true if loan is approved or

false otherwise (based on the pseudocode given above).

LoanApplication class is the main application which has the main() method that

will get the required data from the user, process a loan by calling thedecideLoan()

method ofLoan class and display the result. All of these steps will be repeated until the

user decide to stop which subsequently resulted in the number of loan approved andnumber of loan rejected being printed before the program terminates
