With the following code below...I need help with the following questions. Written in the programming language java with comments explaining the code methods and meaning.

• The search you did in your previous work should now include a memory. The previously searched words are "robots", "fitness", and "wearable". Initially, I printed out the searched keywords clode_date and funds_raised_percent. Now, I need help including what's shown below.
• Memory means that it keeps track of what has been searched. In simple words, you need to store inputs that we give to the search.
• This means the search criteria and timestamp, should be stored in a collection.
• There should be a method to call and print the number of search terms, their timestamps, and frequency

I also provided an image of the JSON file. So if either of the keywords from the code is present in the array, then it should print the category, close_date, funds_raised_percent, and the tag_line
