🔧 Setup and Execution

1. Clone the repository

   git clone https://github.com/nhathao512/Payment-Service-Management-Module.git
   cd PaymentManagementModule

2. Input Files

   • Ensure the input directory contains the required files: IDCard.txt, PaymentInformation.txt, TopUpHistory.txt, and Bill.txt.

3. Compilation

   • Use javac to compile all .java files:

     javac *.java

4. Execution

   • Run the provided test files to validate the implementation of each requirement:

     java TestReq1   # Test Requirement 1
     java TestReq2   # Test Requirement 2
     java Test       # Test Requirements 3-9

5. Output Files

   • Results will be written to the output directory for comparison with expected results in the expected_output folder.
