# Reorder String Equality Check

# Properties

# 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.
