String literals, just like any other Object, should be compared using the equals() method.
Using == and != does not work in general.


The following code:

if (variable == "foo") { /* ... */ }         // Non-Compliant
if (variable != "foo") { /* ... */ }         // Non-Compliant


should be refactored into:

if ("foo".equals(variable)) { /* ... */ }    // Compliant
if (!"foo".equals(variable)) { /* ... */ }   // Compliant
