It is preferable to place string literals on the left-hand side of an ``++equals()++`` or ``++equalsIgnoreCase()++`` method call. This prevents null pointer exceptions from being raised, as a string literal can never be null by definition. == Noncompliant Code Example ---- String myString = null; System.out.println("Equal? " + myString.equals("foo")); // Noncompliant; will raise a NPE System.out.println("Equal? " + (myString != null && myString.equals("foo"))); // Noncompliant; null check could be removed ---- == Compliant Solution ---- System.out.println("Equal?" + "foo".equals(myString)); // properly deals with the null case ---- ifdef::env-github,rspecator-view[] ''' == Implementation Specification (visible only on this page) include::message.adoc[] ''' == Comments And Links (visible only on this page) include::comments-and-links.adoc[] endif::env-github,rspecator-view[]
