# Description
To avoid NullPointerExceptions , it is recommended to put string literals in the left-hand-side of equals() or equalsIgnoreCase() when checking for equality.
# Benefits
This order prevents NullPointerExceptions from being raised, as a string literal can never be null by definition, and therefore makes the code less prone to errors. An example can be seen below.
# Code Changes
Pre
getClass().getName().equals("Foo");
Post
"Foo".equals(getClass().getName());
