Question

Question 4 (3 mark) : Write a Java program to ask the user to input an integer number from the keyboard. The output should indicate whether it is positive, zero, or negative, an even number or an odd number. REQUIREMENTS • Your code should ask user to input an integer number, then decide its sign and parity based on this input. • Your code should use if-else statement. Your code must work exactly as the specification and the output should be exactly the sam as the output example. 5 example of the program output (the texts in bold indicate the user input): Example 1: Property Please input a number: 6 6 is a positive, even number. Example 2: Please input a number: -27 -27 is a negative, odd number. Example 3: Property Please input a number: 25 25 is a positive, odd number. Example 4: Property Please input a number: -16 -16 is a negative, even number. Example 5: Property Please input a number: 0 0 is a zero, even number.

Answer 1

Answer:

Here is the java code as per your requirement

Raw code:

//importing scanner class for input from user

import java.util.Scanner;

//class named Numbers

public class Numbers{

//main

public static void main(String[] args) {

//creating scanner object

Scanner sc = new Scanner(System.in);

//prompt to the user

System.out.print("Property Please input a number: ");

//getting input

int num =sc.nextInt();

//checking if the input is 0

if(num==0) {

System.out.println(num+" is a zero, even number.");

}

//if input is greater than 0 its positive

if(num>0) {

//checking if its odd or even

if(num%2==0) {

System.out.println(num + " is a positive, even number.");

}

else {

System.out.println(num + " is a positive, odd number.");

}

}

//if number is less than 0 its negative

if(num<0) {

//checking if its odd or even

if(num%2==0) {

System.out.println(num + " is a negative, even number.");

}

else {

System.out.println(num + " is a negative, odd number.");

}

}

}

}

Code in the editor:

output:

Console X <terminated> Numbers (Java Application] /Library/Java/JavaVirtual Mac Property Please input a number: 0 O is a zero, even number.

<terminated Numbers (Java Application] /Library/Java/JavaVirtual Mac Property Please input a number: -25 -25 is a negative, odd number.

<terminated> Numbers [Java Application] /Library/Java/JavaVirtual Machines/jdk1.8.0_231.jdk/Con Property Please input a number: 16 16 is a positive, even number.

Console X <terminated Numbers [Java Application] /Library/Java/Javavirtual Property Please input a number: 7 7 is a positive, odd number.
