==== Noncompliant code example
|
|
|
|
[source,java]
|
|
----
|
|
Pattern.compile("(?=a)b"); // Noncompliant, the same character can't be equal to 'a' and 'b' at the same time
|
|
----
|
|
|
|
|
|
==== Compliant solution
|
|
|
|
[source,java]
|
|
----
|
|
Pattern.compile("(?<=a)b");
|
|
Pattern.compile("a(?=b)");
