I have this class constructor:
public Category(int max){
...
}
The thing is, I want to make an array of this class, how do I initialize it?
private Category categories = new Category(max)[4];
Does not work.
UPDATE
Do I need to do something like this?
private Category[] categories = new Category[4];
And then initialize each object?
When you are making an array , you are creating an array of Category. That s an instance of array.
When you are populating the array with Category objects, at that point you use the Category with Const.
Category [] categories = new Category[4];
categories[0] = new Category(10);
You can also do that in-line - make both the array and populate it with values initiated with their constructors at once. Suppose you have a class called Field that has a constructor taking two parameters and you want to construct an array of these ...
Field[] fields = new Field[]{
new Field(1, "Record_Type"),
new Field(3, "Record_SubType"),
new Field(6, "Row_Number"),
...
};
private Category[] categories = new Category[4];
Will be instantiated with 4 null categories, you have to fill the content yourself later.
Or you can try:
private Category[] categories = {new Category(max), new Category(max), new Category(max), new Category(max)};
Initialize it as an array first
Category[] categories = new Categories[4];
categories[0] = new Category(max);
Then initialize each individual element.
