Question

1. Define stubs for the methods called by the below main(). Each stub should print "FIXME: Finish methodName()" followed by a newline, and should return -1. Example output:

import java.util.Scanner;

public class MthdStubsStatistics {

   /* Your solution goes here */

   public static void main() {
      int userNum1 = 0;
      int userNum2 = 0;
      int avgResult = 0;

      userNum1 = getUserNum();
      userNum2 = getUserNum();

      avgResult = computeAvg(userNum1, userNum2);

      System.out.println("Avg: " + avgResult);

      return;
   }
}

2. Using the celsiusToKelvin function as a guide, create a new function, changing the name to kelvinToCelsius, and modifying the function accordingly.

import java.util.Scanner;

public class TemperatureConversion {
   public static double celsiusToKelvin(double valueCelsius) {
      double valueKelvin = 0.0;

      valueKelvin = valueCelsius + 273.15;

      return valueKelvin;
   }

   /* Your solution goes here */

   public static void main (String [] args) {
      double valueC = 0.0;
      double valueK = 0.0;

      valueC = 10.0;
      System.out.println(valueC + " C is " + celsiusToKelvin(valueC) + " K");

      valueK = 283.15;
      System.out.println(valueK + " is " + kelvinToCelsius(valueK) + " C");

      return;
   }
}

3. Complete the second printSalutation() method to print the following given personName "Holly" and customSalutation "Welcome":

import java.util.Scanner;

public class MultipleSalutations {
   public static void printSalutation(String personName) {
      System.out.println("Hello, " + personName);
      return;
   }

//Define void printSalutation(String personName, String customSalutation)...

   /* Your solution goes here */

   public static void main (String [] args) {
      printSalutation("Holly", "Welcome");
      printSalutation("Sanjiv");

      return;
   }
}

Explanation / Answer

1).

import java.util.Scanner;

public class MthdStubsStatistics {

/* Your solution goes here */
public static int getUserNum(){
   System.out.println("FIXME: Finish getUserNum()");
   return -1;
}

public static int computeAvg(int userNum1, int userNum2){
   System.out.println("FIXME: Finish computeAvg()");
   return -1;
}
public static void main(String args[]) {
int userNum1 = 0;
int userNum2 = 0;
int avgResult = 0;

userNum1 = getUserNum();
userNum2 = getUserNum();

avgResult = computeAvg(userNum1, userNum2);

System.out.println("Avg: " + avgResult);

return;
}
}
/*
   Output:
   FIXME: Finish getUserNum()
   FIXME: Finish getUserNum()
   FIXME: Finish computeAvg()
   Avg: -1
*/

2).

import java.util.Scanner;

public class TemperatureConversion {
public static double celsiusToKelvin(double valueCelsius) {
double valueKelvin = 0.0;

valueKelvin = valueCelsius + 273.15;

return valueKelvin;
}

/* Your solution goes here */
public static double kelvinToCelsius(double valueKelvin) {
   double valueCelsius = 0.0;

   valueCelsius = valueKelvin - 273.15;

   return valueCelsius;
}

public static void main (String [] args) {
double valueC = 0.0;
double valueK = 0.0;

valueC = 10.0;
System.out.println(valueC + "C is " + celsiusToKelvin(valueC) + " K");

valueK = 283.15;
System.out.println(valueK + "K is " + kelvinToCelsius(valueK) + " C");

return;
}
}

/*
Output:
   10.0C is 283.15 K
   283.15K is 10.0 C

*/

3).

import java.util.Scanner;

public class MultipleSalutations {
  
public static void printSalutation(String personName) {
System.out.println("Hello, " + personName);
return;
}

//Define void printSalutation(String personName, String customSalutation)...
/* Your solution goes here */
public static void printSalutation(String personName, String customSalutation) {
   System.out.println(customSalutation+", " + personName);
   return;
   }

public static void main (String [] args) {
printSalutation("Holly", "Welcome");
printSalutation("Sanjiv");

return;
}
}

/*
Output:
   Welcome, Holly
   Hello, Sanjiv
*/
