30. Clamping a value between min and max

Let’s assume that we have a pressure regulator that is capable of adjusting the given pressure in a certain range. For instance, if the passed pressure is below the minimum pressure, then the regulator increases the pressure to the minimum pressure. On the other hand, if the passed pressure is higher than the maximum pressure, then the regulator decreases the pressure to the maximum pressure. Moreover, if the passed pressure is between the minimum (inclusive) and maximum (inclusive) pressure, then nothing happens – this is the normal pressure.

Coding this scenario can be done in a straightforward manner, as follows:

private static final int MIN_PRESSURE = 10; 
private static final int MAX_PRESSURE = 50; 
 
public static int adjust(int pressure) { 
         
  if (pressure < MIN_PRESSURE) { 
    return MIN_PRESSURE; 
  } 
         
  if (pressure > MAX_PRESSURE) { 
    return MAX_PRESSURE; 
  } 
         
  return...
