The needless repetition of an operator is usually a typo. There is no reason to write ``++!!!i++`` when ``++!i++`` will do.
|
|
|
|
|
|
On the other hand, the repetition of increment and decrement operators may have been done on purpose, but doing so obfuscates the meaning, and should be simplified.
|
|
|
|
|
|
This rule raises an issue for sequences of: ``++!++``, ``++~++``, ``++-++``, and ``{plus}``.

== Noncompliant Code Example
|
|
|
|
----
|
|
int i = 1;
|
|
|
|
int j = - - -i; // Noncompliant; just use -i
|
|
int k = ~~~i; // Noncompliant; same as i
|
|
int m = + +i; // Noncompliant; operators are useless here
|
|
|
|
boolean b = false;
|
|
boolean c = !!!b; // Noncompliant
|

== Compliant Solution
|
|
|
|
----
|
|
int i = 1;
|
|
|
|
int j = -i;
|
|
int k = ~i;
|
|
int m = i;
|
|
|
|
boolean b = false;
|
|
boolean c = !b;

== Exceptions
|
|
|
|
Overflow handling for GWT compilation using ``++~~++`` is ignored.
