I have summarized various data structures.
First of all, an array is a typical "method of handling multiple data in one".
The representative ones of the array are as follows.
List-Stores in order. (Contents can be duplicated)
Set-Not always in order. (Contents cannot be duplicated)
Map-Stores in pairs.
Java has "container classes for storing data together" corresponding to various data structures.
It is prepared as an API. They belong to the java.util package.
It is called the collection framework </ b>.
From now on, I will learn about the collection and deepen my understanding.
If you make a mistake, thank you for your guidance and encouragement! !! !!
