Question

The main method is where Java begins execution of your program. In this assignment, you will coding other methods in addition to the main method. These additional methods will perform specific functions and, in most cases, return results. Write all your methods in a class named Homework6Methods.java




1 Write a public static method named getMaxOf2Ints that takes in 2 int arguments and returns the Maximum of the 2 values

2Write a public static method named getMinOf2Ints that takes in 2 int arguments and returns the Maximum of the 2 values

3Write a public static method named getMaxOf3Ints that takes in 3 int arguments and returns the Maximum of the 3 values

4Write a public static method named getMedianOf3Ints that takes in 3 int arguments and returns the Median Value of the 3 values

5Write a public static method named printMinOf3Ints that takes in 3 int arguments of type int and prints the minimum value of those 3 ints

Example: “The min is “ + minVal

6Write a public static method named getProdOfAllPositiveInts that takes in 1 int argument and returns the product of all the values between 1 and that number.

If the argument is NON-positive return 0

7Write a public static method named getProdOfAllNegativeInts that takes in 1 int argument and returns the product of all the values between -1 and that number.

If the argument is NON-negative return 0

8Write a public static method named isProdOfAllNegativeIntsNegative that takes in 1 int argument and returns true if the product of all the values between -1 and that number is negative, and false otherwise.

9Write a public static method named getCharAtIndex that takes in 2 arguments, a String s, and an int index. The method should return the char found at the index location of the string or if not found return a ‘?’

10Write a public static method named getCountOfCharInString that takes in 2 arguments, a String s, and a char c. The method should return an int representing the number of times the char was found within the string.

11Write a public static method named getStringReversed that takes in 1 argument of type String and returns the String in reverse order.

12Write a public static method named getStringTitleCased that takes in 1 argument of type String and capitalizes the first letter of each word in the String, then returns the title cased string.

Example:

Input: “the dog ate my homework!” Returns: “The Dog Ate My Homework!”

Input: “tHe Dog atE My HOMEwoRk!” Returns: “The Dog Ate My Homework!”

Input: “THE DOG ATE MY HOMEWORK!” Returns: “The Dog Ate My Homework!”

Answer 1

NOTE:

All the values are directly passed as parameters.

CODE WITH EXPLANATION :

            How to calculate the median value.
            Median is the middle value.
            for the three numbers example 5,4,2 
            the median is calculated as follows
               1)sort the values in ascending order => 2,4,5
               2)Median is the middle value.
               Therefore 4 is the median of 2,4,5
         For 3 numbers it is observed that the median ie middle element will not be maximum and also minimum.
         Hene median calculated using the above strategy.
            */
