What is a Java collection?


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.

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>.

at the end

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! !! !!
