• For ImperialUnits.java, support for " (inches) and ' (feet) was added as valid units for measurements. This change resolves issue support " and ' as a valid units for inches and feet #3551.
• For QuantityTypeTest.java, added new test methods (testUnitAliases and testFormattedUnits) to validate the changes in ImperialUnits.java and ensure that the parsing and formatting of these units work correctly.
• Removing unused variable BIG_DECIMAL_2 in ColorUtil.java was addressed as part of corrective maintenance.

2. The graph you created and its completeness (3 marks)
   

3. The impact or insights gained from the analysis (1 mark)

• Adding " and ' as valid units enhances usability and aligns with user expectations for measurement systems. The new test methods verify that the added units (" and ') are correctly parsed and formatted. This ensures robustness for the new feature. The removal of BIG_DECIMAL_2 streamlines ColorUtil.java and reduces potential confusion or maintenance overhead.
