Question

Ans In Java Please

Homework 6-1

So far in this course, all of your programs have been written to be fully contained inside a single method named main. 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

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

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

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

5. Write 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

6. Write 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

7. Write 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

8. Write 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.

9. Write 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 ‘?’

10. Write 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.

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

12. Write 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!”

Please complete all the Participation and Challenge activities in the above sections. This work must be completed in your textbook ZYBooks -- CMP-167: Programming Methods I

No other forms of submission will be accepted.
