Collection and array length checks must be sensibleJAVA-W1005

A comparison involving the size of a collection or an array was found, which is always guaranteed to be either true or false.

This is a generally frivolous action and may have been caused by a typo. If this was done to prevent certain code from executing or to ensure some code always executes for debugging purposes, remove it. All debugging-related code changes should be cleaned up after their purpose is served.

Consider revisiting the expression to make sure such a comparison was intended.

Bad Practice

Certain comparisons don't ever make sense when dealing with the size of a collection or an array's length.

Consider:

someArray.length < 0

The expression above always evaluates to false since it is impossible for an array to have a negative length.

Similarly, the following comparison is functionally useless:

someCollection.size() >= 0

The usual state of affairs is that collections cannot have negative sizes. It thus makes no sense to explicitly check if the size of a collection is non-negative as has been done here.

Recommended

Do not perform comparisons that are guaranteed to result in the same value everytime.

if (coll.size() > 24) {
    // ...
}

If you need to check for when a collection is empty, you can use the isEmpty() method to do so:

if (coll.isEmpty()) {
    // ...
}
