Question

CST-117 In-Class Assignment 7

A method stub, or signature, is the first line of a method.

Write a class that contains the following “stubs” for methods used in measurement conversion. You do not have to implement the methods.

Here’s an example:

Write a void method that takes an integer for the number of millimeters and displays the number of meters.

Correct response:

public void showMeters(int numMillimeters){}

1. Write a method that takes two integers and displays their sum.

2. Write a method that takes five doubles and returns their average.

3. Write a method that returns the sum of two randomly generated integers.

4. Write a method that takes three integers and returns true if their sum is divisible by 3 and false otherwise.

5. Write a method that takes two strings and displays the string that has fewer characters.

6. Write a method that takes an array of doubles and returns the largest value in the array.

7. Write a method that generates and returns an array of fifty integer values.

8. Write a method that takes two bool variables and return true if they have the same value and false otherwise.

9. Write a method that takes an int and a double and returns their product.

10. Write a method that takes a two-dimensional array of integers and returns the average of the entries.

Answer 1

Write a method that takes two integers and displays their sum.

public void displaySum(int numOne, int numTwo){
}

Write a method that takes five doubles and returns their average.
public double averageOfFive(double num1, double num2, double num3, double num4, double num5){
}

Write a method that returns the sum of two randomly generated integers.
public int sumOfTwoRandomNumbers(){
}

Write a method that takes three integers and returns true if their sum is divisible by 3 and false otherwise.
public boolean isDivisibleByThree(int num1, int num2, int num3){
}

Write a method that takes two strings and displays the string that has fewer characters.
public void displayShortestString (String strOne, string strTwo){

}

Write a method that takes an array of doubles and returns the largest value in the array.
public double getLargest(double numbers[]){
}

Write a method that generates and returns an array of fifty integer values.
public int[] getFiftyInts(){
}

Write a method that takes two bool variables and return true if they have the same value and false otherwise.
public bool areSame(bool flagOne, bool flagTwo){
}

Write a method that takes an int and a double and returns their product.
public double getProduct(int num1, double num2){
}

or

public double getProduct(double num1, int num2){
}

Write a method that takes a two-dimensional array of integers and returns the average of the entries.

public double getAverage(int numbers[][]){
}
