Java: @NonNull for int?

Question

I'm looking for @NonNull equivalent Java annotation for primitive data type. I know primitive data cannot be null, but I wasn't able to find an alternative.

What I'd like to achieve is logically equivalent to:

int mPageNumber;

public void updatePage(@NonNull final Integer nonNull) {
    mPageNumber = nonNull.intValue();
}

I tried:

int mPageNumber;

public void updatePage(@NonNull final int nonNull) {
    mPageNumber = nonNull;
}

And I get the following lint warning:

Primitive type members cannot be annotated. This inspection reports problems related to @Nullable and @NotNull annotations usage configured in Constant conditions & exceptions inspection.

What can I put in place of @NonNull and Integer in updatePage method above, so that I can have int as an argument, not Integer?

Answer 1

You should change the mPageNumber type to Integer.

As int type can not be null, but Integer can do.
