Answer:
Programming is everywhere in the modern world and meets you in the street, your workplace, and the local grocery store. You interact with bar-code scanners regularly, and you almost certainly use lots of code while working, whether you're using a word processor to write a letter or an email platform to send messages. Programs used in real-world environments should also be programmed in the real world, so we have developed a new programming paradigm, “Real-World Programming (RWP),” which enables users to make programs for handling real-world environments as well as data in computers
Answer:
There are no statements in the question, so I explained the whole code.
Explanation:
A map consists of key - value pairs. The put method allows you to insert values in the map. The first parameter in the put method is the key, and the second one is the value. Also, the keys must be unique.
For example, map.put("123", "John Smith"); -> key = 123, value = John Smith
Even though the key 123 is set to John Smith at the beginning, it will have the updated value Steve Yao at the end. That is because the keys are unique.
Note that the key 222 also has Steve Yao for the value, that is totally acceptable.
