Write a program to check an integer is Even or Odd<\/h2>\r\n

In this post, we will write a java program to check if the entered integer is Even or odd number. We will use Eclipse IDE in this example.<\/p>\r\n

IPO Chart<\/h3>\r\n

IPO stands for Input- Process – Output<\/strong>. IPO is a handy tool to analyze the program input, process and outputs to the flowchart\/program. Beginners are recommended to create the IPO in a table format. Analyze the problem statement and think about the program inputs, processing steps and what the problem should display as output.\u00a0\u00a0<\/p>\r\n

Input<\/strong> – User entered number.<\/p>\r\n

Process<\/strong><\/p>\r\n

number%2 == 0 –> EVEN<\/p>\r\n

Else —> ODD<\/p>\r\n

Output<\/strong><\/p>\r\n

Display whether the input number is odd or even number.\u00a0<\/p>\r\n

Java Program<\/h3>\r\n

Launch Eclipse IDE. Create a new Java package and Java class.\u00a0<\/p>\r\n

Add the program code within the main method.\u00a0<\/p>\r\n

 <\/p>\r\n

package com.testingdocs.programs;\r\n\r\nimport java.util.Scanner;\r\n\r\n\/**************************************************\r\n * EvenOdd.java\r\n * @program   \t: Even or Odd check\r\n * @web        \t: www.TestingDocs.com\r\n * @version     : 1.0\r\n **************************************************\/\r\n\r\npublic class EvenOdd {\r\n\t\/\/ main method\r\n\tpublic static void main(String[] args) {\r\n\t\t\/\/ Take input from user\r\n\t\tScanner keyboard = new Scanner(System.in);\r\n\t\tSystem.out.print(\"Please enter the number :=\");\r\n\t\tint inputNumber = keyboard.nextInt();\r\n\t\t\/\/ Output \r\n\t\tif(inputNumber % 2 == 0 ) {\r\n\t\t\tSystem.out.println(\"The number \" + 
inputNumber + \" is EVEN.\");\r\n\t\t}else {\r\n\t\t\tSystem.out.println(\"The number \" + 
inputNumber + \" is ODD.\");\r\n\t\t} \/\/ end if\r\n\t} \/\/ end main\r\n} \/\/ end class\r\n\r\n\r\n<\/pre>\r\n
 <\/p>\r\n
Screenshot<\/h3>\r\n
Screenshot of the program in Eclipse IDE.<\/p>\r\n
\"Even<\/p>\r\n
Sample Output<\/h3>\r\n
Save the program code and execute the Java application. Execute some test cases to verify the program output.\u00a0<\/p>\r\n
To run the Java application, choose the menu option<\/p>\r\n
Right click >> Run as >> Java application<\/strong><\/p>\r\n
The program will prompt to enter a number.\u00a0<\/p>\r\n
Output<\/strong><\/p>\r\n
Please enter the number :=3
The number 3 is ODD.<\/p>\r\n
