Comparison of String parameter using == or !=

The code in Admin.Admin.createNewUser(String, String, String, String, String, String) contains a comparison of strings using ==. This can cause unexpected behaviors in the application due to comparing references rather than contents.

To reproduce:

• Go to Admin.Admin.createNewUser(String, String, String, String, String, String) in the src/main/java folder
• Locate the if statement on line 343
• Identify the use of == to compare strings

Expected: The createNewUser method should compare String parameters using the equals() method for value comparison to ensure correct behavior and avoid potential bugs related to string comparison.
Actual: == is used to compare strings which compares their references rather than their contents.

This looks like a really cool project from the screenshots. How do I run it?

Possible Null pointer dereference

The code in Admin.Admin.getSupplierNames() contains a possible null pointer dereference where the variable "data" is dereferenced without first checking if it is null. This can cause potential crashes when the application is ran.

To reproduce:

• Go to Admin.Admin.getSupplierNames() in the src/main/java folder
• Go to line 834 and locate the "size" initialization
• Identify that it doesn't check if "data" is null before using it

Expected: Variables should be checked if they're null before dereferencing to avoid potential NullPointerExceptions and ensure stability and reliability
Actual: The code doesn't check for null which may result in a crash under certain circumstances.
