Assigning enum a integer value

Question

hellow, please is there any way to assign items of enum type a integer value.
I have enum SizeOfGrid
9x9,
16x16,
25x25,
and i need to assign an integer value to each items
so i can create new grids like new Grid(9x9.value) or something
and not using switch each time like:
Switch(sizeOfGrid)
case 9x9:
value = 9;
etc.
I need to preserve the type enum, because i need it to be type-safe.
So please is there any way to do that? Thanks a lot.

Answer 1

does your code even compile right now? i thought enum values could not start with a number.
when you declare an enum it gets compiled to a class, and the values that you specify are instances of that class, so you can give it any methods you like, for example:
enum SizeOfGrid {
    SMALL(9),
    MEDIUM(16),
    LARGE(25);
    private int size;
    private SizeOfGrid(int size) {
        this.size = size;
    public int getSize() {
        return size;
}Then to get back the size you can do:
int size = SizeOfGrid.SMALL.getSize();
