Answer to Question #243155 in Java | JSP | JSF for guru

Question

 Given any whole number from user input, check whether it’s a positive or negative number. If the number is negative then increment it by 3 and multiply the result by 4, however if it’s a positive number then decrement by 4 and multiply it by 3.

a) Create a flowchart to be followed to solve the above task

b) Create a java program using your flowchart and see samples below

Sample run 1:

Enter a whole number: 4

Output: The Number 4 is above zero hence,

Result of the calculations = 0

Sample run 2:

Enter a whole number: -5

Output: The Number -5 is below zero hence,

esult of the calculations = -8

Answer 1

import java.util.Scanner;


public class Main {


	public static void main(String[] args) {
		Scanner keyBoard = new Scanner(System.in);
		System.out.print("Enter a whole number: ");
		int number = keyBoard.nextInt();
		int result = 0;
		if (number > 0) {
			result = (number - 4) * 3;
			System.out.println("The number " + number + " is above zero hence");
		} else if (number < 0) {
			result = (number + 3) * 4;
			System.out.println("The number " + number + " is below zero hence");
		}
		System.out.println("Result of the calculations = " + result);
		keyBoard.close();
	}
}
