Overview: This project analyzes survey data from lung cancer patients to extract insights about their quality of life. The data includes both demographic and medical information. We built a custom hash table to store and analyze the responses, and implemented several methods to compute distributions and life quality statistics.

How to Run the Project:

1. Make sure the following files are in the same directory:
   Response.java, CustomHashTable.java, ReadFile.java, SurveyDataAnalyzer.java, Tests.java, and responses.txt

2. To run the analysis, execute: SurveyDataAnalyzer.java

3. To run the test suite, execute: Tests.java

File Format: The program expects the responses.txt file to contain tab-separated values (TSV), not comma-separated, with the following fields:

ID, Gender, Age, Residence, Education, IncomeSource, MaritalStatus, Smoker, Year, 
Q9, Q10, Q11, Q12, Q13, Q14, Q15, Q16, Q17, Q18, Q19, Q20, Q21, Q22, 
Q23, Q24, Q25, Q26, Q27, Q28, Q29, Q30

Each row should have 31 values. The gender field is expected to be a letter: "F", "M", "O" (Other), or "-" (Unknown). You can adjust the data preprocessing if the dataset uses numeric codes instead.

Implemented Features: We implemented the following 20 analysis methods in SurveyDataAnalyzer.java:

1. genderDistribution()
2. ageGroupDistribution()
3. residenceDistribution()
4. educationDistribution()
5. incomeDistribution()
6. maritalDistribution()
7. smokerDistribution()
8. lifeQualityGeneral()
9. lifeQualityGenderBased()
10. lifeQualityAgeBased()
11. lifeQualityResidenceBased()
12. lifeQualityEducationBased()
13. lifeQualityIncomeBased()
14. lifeQualityMaritalBased()
15. lifeQualitySmokerBased()
16. mostCommonTreatment()
17. mostCommonSymptoms()
18. mostCommonLifeAspects()
19. lifeQualityMixConditionsBased()
20. lifeQualityResponseBased()

Each method has been tested using sample expected outputs in the Tests.java file.
