== Why is this an issue?

include::../description.adoc[]

To match a literal string instead of a regular expression, either all special characters should be escaped, the `Pattern.LITERAL` flag or methods that don't use regular expressions should be used.


=== Noncompliant code example

[source,java]
----
Pattern.compile("([");
str.matches("([");
str.replaceAll("([", "{");
str.matches("(\\w+-(\\d+)");
----


=== Compliant solution

[source,java]
----
Pattern.compile("\\(\\[");
Pattern.compile("([", Pattern.LITERAL);
str.equals("([");
str.replace("([", "{");
str.matches("(\\w+)-(\\d+)");
