Java By Comparison

Avoid Unnecessary Comparisons

class Laboratory {

    Microscope microscope;

    Result analyze(Sample sample) {
        if (microscope.isInorganic(sample) == true) {
            return Result.INORGANIC;
        } else {
            return analyzeOrganic(sample);
        }
    }

    private Result analyzeOrganic(Sample sample) {
        if (microscope.isHumanoid(sample) == false) {
            return Result.ALIEN;
        } else {
            return Result.HUMANOID;
        }
    }
}

The first logical conditions you learned to write probably consisted of integers and comparison operators, and a beginner might use that same way of implementing conditions with boolean values. But those comparisons are completely unnecessary—they’re like noise in your code.
