Question
1. Assume that two classes 'Temperature' and 'Sensor' have been defined. 'Temperature' has a constructor that accepts a double parameter. 'Sensor' has a methodnamed 'getReading' which returns the sensor's current reading (a double). Write a static method 'create' (that could be added to the 'Temperature' class) that accepts a 'Sensor' object. 'create' gets the value of the current reading of the 'Sensor' object, and returns a new 'Temperature' object that is based on this reading.
2.Assume the availability of class named DateManager that provides a static method, printTodaysDate, that accepts no arguments and returns no value. Write a statement that calls printTodaysDate.
3.Assume the availability of class named DataTransmitter that provides a static method, sendSignal that takes no arguments. Write the code for invoking this method.
4.Write the code for invoking a static method named sendNumber , provided by the DataTransmitter class. There is one int argument for this method. Invoke this method and use the number 5 as an argument.
5.Write the code for invoking a static method named sendDouble, provided by the DataTransmitter class. There is one double argument for this method.
Assume that a double variable called x has already been declared and initialized to some value. Use this variable's value as an argument in your methodinvocation.
Explanation / Answer
Since you have not provided the language of your preference, I am providing the code in Java.
CODE
==================
import java.util.Date;
class DateManager {
public static void printTodaysDate () {
Date today = new Date();
System.out.println(today);
}
}
class DataTransmitter {
public static void sendSignal () {
}
public static void sendNumber (int num) {
}
public static void sendDouble (double num) {
}
}
public class Main
{
public static void main(String[] args)
{
DateManager.printTodaysDate();
DataTransmitter.sendNumber(5);
DataTransmitter.sendDouble(x);
} // end main()
}
