Selection statement not working as expected

Question

The hotter and cooler methods are the ones in question. It just prints "Cannot go below the minimum temperature" ,no matter what value I set increment, min, or max to. It also does not change the value of temperature.
I've already tried adding parentheses like this : if ((temperature - incremen)t <= min)
public class Heater
    //the current temperature
    private int temperature;
    //the minimum temperature
    private int min;
    //the maximum temperature
    private int max;
    private int increment;
    public Heater(int minimum, int maximum)
        min = minimum;
        max = maximum;
        increment = 5;
        temperature = 15;
    //decreases the temperature by 5
    public void cooler()
        if (temperature - increment <= min)
        temperature = temperature - increment;
        else
        System.out.println("Cannot go below the minimum temperature");
    //increases the temperature by 5
    public void hotter()
        if (temperature + increment >= max)
        temperature = temperature + increment;
        else
            System.out.println("Cannot go above the maximum temperature");
   //sets the amount to increment the heat by
    public void setIncrement(int incrementAmount)
        if (incrementAmount > 0)
        increment = incrementAmount;
        else
        System.out.println("Please enter a positive amount");
    //returns the current temperature
    public int getTemperature()
        return temperature;
}

Hi,
you mixed the conditions. you want to stay above minimum and below maximum:
if (temperature - increment >= min)
if (temperature + increment <= max)
