Check Even-Odd:-Example
Now, you have to learn about the syntax of If - Else construct. How the If -
Else construct used to flow the program control as for as needed. If - Else
construct has illustrated by a given example.
Given example reads a integer value and check weather number is Odd or Even. In this
example you will learn how to determine the Even or Odd for the
given number entered through the keyboard. If the given condition is true then
print the message Given number is Even otherwise
the control of the program will jumps in the else
block and print the message Given number is Odd. In
this example a special exception has been also used, that is NumberFormatException
which holds the error during the checking the entered data format. Entered data
must be a number not a character or string. If you enter anything except numeric
value then normal flow of the program is sent to the catch block and print the
specified message. Full running code is provided with the example.
Here is the code of the program:-
|
import java.io.*;
public class IfElse{
public static void main(String[] args) throws IOException{
try{
int n;
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
n = Integer.parseInt(in.readLine());
if (n % 2 == 0)
{
System.out.println("Given number is Even.");
}
else
{
System.out.println("Given number is Odd.");
}
}
catch(NumberFormatException e){
System.out.println(e.getMessage() + " is not a numeric value.");
System.exit(0);
}
}
}
