Two helper methods to improve semantics of range comparison.

Bounds.java

    private boolean isOutsideRange(int i, int lowerBound, int upperBound) {
        return (i < lowerBound || upperBound < i);
    }

    private boolean isInsideRange(int i, int lowerBound, int upperBound) {
        return (i < lowerBound && upperBound < i);
    }
