Question

Java code write a program that, with given three integers from keyboard, determine whether each integer is odd, even, select largest and smallest, and calculate the sum, average, and product. Then, you display the results on the screen. You will use Scanner class to make user input, and use if statement to determine largest, smallest number as well as even or odd number. variables: Define your  variables and  data  type of  each  variable.    Include  Scanner and DecimalFormat class:  Import Scanner  classs and create Scanner object. Import DecimalFormat class and  create   DecimalFormat  object Make use input rom keyboard: Input three integers  from  keyboard and save it to local variable should be one line input. Calculate sum, average, product,and determine whether  each  number  is  odd  or even. Calculate  sum, average  and product  save it  to local  variable. Determine odd  or even  and save it  to  local  variable. Decide largest  and  smallest  number: Select  the  largest  number among  three integers – use  if only statement only. Select  the smallest number among three integers  –  use if only  statement only not else or if else just if statement. Display the result  on the screen your result  should be formatt as follows: Print whether each number  is odd or  integers use if only statement only. Print  largest,  smallest,  sum,  average, and product of  three integers. (the three intergers must be on the same line when displayed on the screen)

code public class calculate_int {

public static void main(String[] args)

{ //define variable name and their type.

//create scanner object //

Create a DecimalFormat object

//input three integer

//calculate sum, average, product

//determine odd or even and save it to local variable

//get largest number

//get smallest number

/****************************** print the results of three integers, sum, product, average, smallest, and largest number, on the screen. *******************************/ System.out.println(); System.out.println(" R E S U L T"); System.out.println();

// print whether each number is even or odd. -

// print largest, smallest, sum, average, product

System.out.println(" Have a nice day

System.out.println();

System.out.println("Calculated by: xxx"); System.out.println();

}

}
