        • pitfall

        Why is this an issue?

        It is needlessly complex to invert the result of a boolean comparison. The opposite comparison should be made instead.

        Noncompliant code example

        if ( !(a == 2)) { ...}  // Noncompliant
        boolean b = !(i < 10);  // Noncompliant
        

        Compliant solution

        if (a != 2) { ...}
        boolean b = (i >= 10);
