Program written in Java is as follows
See comments for explanations
import java.util.Scanner;
public class CheckRange {
public static void main (String [] args)
{
// This line allows the program accept user input
Scanner input = new Scanner(System.in);
//This line declares variable for user input
int num;
//This line prompts user for input
System.out.print("Number: ");
//This line gets user input
num = input.nextInt();
/* The following if statement checks if the user input is greater than 5 and less than 20 */
if (num > 5 && num <= 20)
{
/* This line is executed if the above condition is true */
System.out.print(num+" is greater than 5 and less than 20");
}
else
{
/*If the condition is not true, this line is executed*/
System.out.print(num+" is not within specified range");
}
// The if condition ends here
}
}
