Like when a seed drops on the ground, and a bee come to take some honey. It sticks to the bee and where the bee goes, the bee will rub it off and the seed will start to grow.
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.
Windows and linux are best in my opinion! Linux is not used by many people but a lot of apps can't be used for linux so best is to use windows. But Mac is not bad too. Hope I helped and have a nice day!
