array of structs in Java

(No points please - a few additional examples)

For a small arrays

//create array of 3 objects
Student[] students = { new Student(), new Student(), new Student() };

For larger arrays

//create array of 1000 objects
Student[] students = new Student[1000];
for (int i = 0; i < students.length; i++) {
      students[i] = new Student();
}
            
For a varying size you could use a List instead of an array

List studentList = new ArrayList();
for (int i = 0; i < 1000; i++) {
      studentList.add(new Student());
}

Thanks! That means that the use of arrey of structs is "useless" in JAVA, since we have Arraylists?
Question: arraylists behave like linked lists with pointers in C?

Not useless, but used much less than in C. In C, an array is the primary (and without additional libraries the only) choice of container, while in Java you have dynamic containers (ArrayList, LinkedList, HashMap and some rare ones) for ease of use and arrays for speed.

ArrayList behaves like array (indexing is fast, addition may require reallocation and copying), only with dynamic length, for linked list is clas... what is your guess :-)? ... LinkedList.

There are no structs in Java, only classes. Of course class without methods and with public fields is in fact a struct. In C code you than usually have a bunch of functions to work with the struct. When rewriting the code into Java, these should become methods of the "struct", turning it into full-fledged Java class.

Thanks again!
What is your advice, to learn first C++ or Java, while coming from C?
