Enter would create a new line, thus allowing you to enter a paragraph, on some applications you can use "Shift+Enter" if it is an IM application like Skype.
Answer:
The solution code is written in Java
- import java.util.Scanner;
-
- public class Main {
- public static void main (String [] args) {
-
- Scanner inStream = new Scanner(System.in);
- System.out.print("Please input a number (1 - 10): ");
- int num = inStream.nextInt();
-
- if(num < 1 || num > 10){
- System.out.println("The input must be between 1 - 10");
- }else{
- switch(num){
- case 1:
- System.out.println("I");
- break;
- case 2:
- System.out.println("II");
- break;
- case 3:
- System.out.println("III");
- break;
- case 4:
- System.out.println("IV");
- break;
- case 5:
- System.out.println("V");
- break;
- case 6:
- System.out.println("VI");
- break;
- case 7:
- System.out.println("VII");
- break;
- case 8:
- System.out.println("VIII");
- break;
- case 9:
- System.out.println("IX");
- break;
- case 10:
- System.out.println("X");
- break;
- }
- }
- }
- }
Explanation:
The first part of this program (Line 6 - 8) is to get input number from user using Scanner object. Input validation has been done to check if the input number is in the acceptable range (Line 10). If not, an error message will be displayed (Line 11).
If the input number is in the range of 1 - 10, the number will go through a series of switch statements checking. If the number meet the condition in one of the switch cases, it will print the corresponding roman numeral specified in the case block (Line 13 - 44). For example, if input number is 9, the case 9 condition is met and "IX" will be printed.
About a database. A data dictionary defines the structure of the database itself (not that of the data held in the database) and is used in control and maintenance of large databases. Among other items of information, it records (1) what data is stored, (2) name, description, and characteristics of each data element, (3) types of relationships between data elements, (4) access rights and frequency of access. Also called system dictionary when used in the context of a system design
