Question

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 Minimum of the 2 values
3. Write apublic 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!”
