This might be educational: https://docs.oracle.com/javase/8/docs/api/java/util/Optional.html

There are issues that the Optional class alleviates that are common enough to be documented: https://www.jetbrains.com/help/inspectopedia/ConditionalCanBeOptional.html (more detail is available at places like https://github.com/JetBrains/intellij-community/blob/a2d32ec64ed0fb37c7cc97856aa94cce95b17ee5/java/java-impl/src/inspectionDescriptions/ConditionalCanBeOptional.html (I believe this information used to be visible with the "inspectopedia" URLs but I don't see that today))
