Subsequent steps can be fused into Stream API chain

Detects transformations outside a Stream API chain that could be incorporated into it.

Example:

After the conversion:

Note that sometimes the converted stream chain may replace explicit ArrayList with Collectors.toList() or explicit HashSet with Collectors.toSet(). The current library implementation uses these collections internally. However, this approach is not very reliable and might change in the future altering the semantics of your code.

If you are concerned about it, use the Do not suggest 'toList()' or 'toSet()' collectors option to suggest Collectors.toCollection() instead of toList and toSet collectors.

This inspection depends on the Java feature 'Stream and Optional API', which is available since Java 8.
