I don’t understand how to initialize an array that is the class

Question

ItemArray Is the class. I have to Initialize the size of the array (the array is the class) to be the size passed Into the constructor below. I don’t know how to do that though.

public ItemArray(int size) {}

Answer 1

In the main method

ItemArray obj = new ItemArray(/* pass your value */);

Answer 2

Do you mean something like this?

public class ItemArray {

//your variable
int size;

//your constructor
public ItemArray(int size){

//this.size means your variable
//int size is the variable from outside

this.size = size;

}

}
