Inplementing boolean values [closed]

I am trying to make the code more efficient, but don’t know how to apply it in my code. What I have in mind is changing the integers insideIsGreater and outsideIsGreater into boolean values. The only problem after that is that I do not know where to begin changing my code. Does anyone care to help?

int amountPassed = 0;
int insideIsGreater = 0;
int outsideIsGreater = 0;

for (Measurement measurement : measurements) {

    double outsideTemp = measurement.getOutsideTemp();  // gets the outside temperature
    double insideTemp = measurement.getInsideTemp();    // gets the inside temperature

    if (outsideTemp > insideTemp) {
        if (outsideIsGreater == 0) {
            amountPassed++;
            outsideIsGreater += 1;
            insideIsGreater = 0;
        }
    } else {
        if (insideTemp > outsideTemp) {
            if (insideIsGreater == 0) {
                amountPassed++;
                insideIsGreater += 1;
                outsideIsGreater = 0;
            }
        }
    }
}

Answer

int amountPassed = 0;
boolean isInsideIsGreater = false;
boolean isOutsideIsGreater = false;

for (Measurement measurement : measurements) {
    double outsideTemp = measurement.getOutsideTemp();  // gets the outside temperature
    double insideTemp = measurement.getInsideTemp();    // gets the inside temperature
        
    if (outsideTemp > insideTemp) {
        if (!isOutsideIsGreater) {
            amountPassed++;
        }
        isOutsideIsGreater = true;
        isInsideIsGreater = false;
    } else if (insideTemp > outsideTemp) {
        if (!isInsideIsGreater) {
            amountPassed++;
        }
        isInsideIsGreater = true;
        isOutsideIsGreater = false;
    } else {    // temperature is same
        isInsideIsGreater = false;
        isOutsideIsGreater = false;
    }
}
