A method called getStatistics that takes an array of integers and an integer, and returns a double value based on the value of the integer parameter as follows: •If the value of the integer parameter is 1, it returns the summation of the array elements. • If the value of the integer parameter is 2, it returns the average of the array elements. • If the value of the integer parameter is 3, it returns the maximum value in the • If the value of the integer parameter is 4, it returns the minimum value in the array. If the value of the integer parameter is 5, it returns the variance of the array elements whose equation is as follows: array. E(x; – x)? п — 1 ī is the average, and n is the number of elements in the array. •If the value of the integer parameter is none of the above, the method must print the statement "Invalid Choice - ZERO returned" and returns 0.

Solve question 2 please, java language
Write a program that includes in its MainClass the following methods: 1. A method called printArray that takes an array of integer values and a boolean value. The method prints the array elements on the same line with one space between each two elements. If the boolean value is true, the elements must be printed in their original order, if it is false they must be printed in reverse order. The method should print a new line after printing the array elements. 2. A method called getStatistics that takes an array of integers and an integer, and returns a double value based on the value of the integer parameter as follows: • If the value of the integer parameter is 1, it returns the summation of the array elements. • If the value of the integer parameter is 2, it returns the average of the array elements. • If the value of the integer parameter is 3, it returns the maximum value in the array. • If the value of the integer parameter is 4, it returns the minimum value in the array. • If value of the integer parameter is 5, it returns the variance of the array elements whose equation is as follows: E(x; – x)2 п — 1 x is the average, and n is the number of elements in the array. If the value of the integer parameter is none of the above, the method must print the statement "Invalid Choice – ZERO returned" and returns 0. 3. A method called isAscendingOrdered that takes an array of integers and returns true if it's ordered ascendingly and false otherwise. 4. A method called shiftAndFill that takes an array of integers and a variable length argument list of integers. The method must shift the array elements to the right and fill the emptied indices with the values in the variable length argument. Note that this method must not create a new array, it must modify the array in its place. Moreover, it must make sure the number of values in the variable length argument is less that the array length. If not, the array must not be modified. Similarly, if there are no values passed in the variable length argument, the array must not be modified. For example, if the passed array is 6, 2, 5, 1, 8, and the values 10, 9 are passed in the variable length argument, after invoking the method the array must become: 10, 9, 6, 2, 5
