Create a class named Problem1, and create a main method, inside the main method prompt the user to enter a positive integer n. The program (Java) must error check (keep prompting and reading integers until you get a positive integer n). The program then will create an integer array arr of size n, and fill up that array with random integers between 1 and 500. - Create a method named getMax, which takes an integer array arr and returns an integer, the method should find the maximum value in the integer array arr. - Create a method named getMin, which takes an integer array arr and returns an integer, the method should find the minimum value in the integer array arr. - Create a method named sumValues, which takes an integer array arr and returns an integer, the method should find the sum of all values in the integer array arr.

- Create a method named getMax, which takes an integer array arr and returns an integer, the method should find the maximum value in the integer array arr.
- Create a method named getMin, which takes an integer array arr and returns an integer, the method should find the minimum value in the integer array arr.
- Create a method named sumValues, which takes an integer array arr and returns an integer, the method should find the sum of all values in the integer array arr.
- Create a method named getAverage, which takes an integer array arr and returns a double, the method should find the average of all values in the integer array arr.
- Create a method named greaterThanAverage, which takes an integer array arr and returns an integer, the method should find how many values were greater than average in the integer array arr.
- Create a method named countInc, which takes an integer array arr and returns an integer, the method should find how many times subsequent value increases (the next value is bigger) in the integer array arr.
- Create a method named countDec, which takes an integer array arr and returns an integer, the method should find how many times subsequent value decreases (the next value is smaller) in the integer array arr.
- Create a method named printArray, which takes an integer array arr and returns no value, the method prints the entire array arr.
- Create a method named printArray3PerLn, which takes an integer array arr and returns no value, the method prints the entire array arr with at most 3 elements per line.
- Make the proper calls from the main method to test all the methods listed above.
