Good Day, I have a project to do where I have to create a database with Redis bit arrays data type and write a Java code to access the database with a GUI drop down menu. I was able to implement the code with sorted set commands but the specification I was given was with bit arrays data type and commands. From my understanding bit arrays operate on strings. Please how would I go about this? Kindly find attached my project below and images of the gui.
