Write a temperature class.In addition to converting between Celsius and Fahrenheit also include Kelvin. The class has read(), add(Temperature), subtract(Temperature), Multiply(Temperature), divide(double), equals(Temperature), toKelvin(), toFarhrenheit(), toCelsius(), and toString() methods. Methods add , subtract, multiply and divide all return a Temperature.

{ Static method written by you.
}
public static Temperature getAverage(Temperature[] array)

}
}I'm having problems with this part:
readTemperatures(tempArray);// must write this method
tempAve = getAverage(tempArray); // must write this method
System.out.println("the average of the array of temperatures is " + tempAve );
}
public static void readTemperatures(Temperature[] array)
{ Static method written by you.
}
public static Temperature getAverage(Temperature[] array)
{ Static method written by you
}I pretty much have the whole assignment complete, but I am having trouble with this last part. This is what I have so far and I'm not sure where to go from here. Any help would be greatly appreciated!
Temperature tempArray [] = new Temperature [ARRAY_SIZE];
{
for (int i = 0; i < tempArray.length; i++)
{
tempArray[i]= new Temperature();
}
