2023 FRQ:

A.

public void cleanData(double lower, double upper) {
    // iterator to safely remove elements from the ArrayList
    Iterator<Double> iterator = temperatures.iterator();
    while (iterator.hasNext()) {
        double temp = iterator.next();
        if (temp < lower || temp > upper) {
            iterator.remove();
        }
    }
}

Iterates and compares each value to the upper and lower.

B.

public int longestHeatWave(double threshold) {
    int maxHeatWaveLength = 0; // The longest heatwave length
    int currentHeatWaveLength = 0; // The current heatwave length

    for (double temp : temperatures) {
        if (temp > threshold) {
            currentHeatWaveLength++;
            maxHeatWaveLength = Math.max(maxHeatWaveLength, currentHeatWaveLength);
        } else {
            currentHeatWaveLength = 0; // Reset if temperature drops below threshold
        }
    }

    return maxHeatWaveLength;
}

Iterates and updates length of streak, udates max if longer is found
