Question about the task

Archived

Enter an integer from the keyboard in the range 1 - 999. Display a string description as follows:
"even single-digit number" - if the number is even and has one digit,
"odd single-digit number" - if the number is odd and has one digit,
"even two-digit number" - if the number is even and has two digits,
"odd two-digit number" - if the number is odd and has two digits,
"even three-digit number" - if the number is even and has three digits,
"odd three-digit number" - if the number is odd and has three digits.
If the entered number does not fall in the range 1 - 999, don't display anything.

Example for 100:
even three-digit number

Example for 51:
odd two-digit number

Requirements:

The program should read one number from the keyboard.
The program should use System.out.println() or System.out.print()..
If the number is even and has one digit, display "even single-digit number".
If the number is odd and has one digit, display "odd single-digit number".
If the number is even and has two digits, display "even two-digit number".
If the number is odd and has two digits, display "odd two-digit number".
If the number is even and has three digits, display "even three-digit number".
If the number is odd and has three digits, display "odd three-digit number".
If the entered number doesn't fall in the range 1 - 999, don't display anything
The program should display a string description of the number and nothing else.

package com.codegym.task.task04.task0427; /* Describing numbers */ import java.io.*; import java.util.Scanner; public class Solution { public static void main(String[] args) throws Exception { //write your code here Scanner sc = new Scanner(System.in); int num = sc.nextInt(); if(num <= 10 ) { if(num % 2 == 0) { System.out.println("even single-digit number"); } else { System.out.println("odd single-digit number"); } } else if(num > 10 && num < 101) { if(num % 2 == 0) { System.out.println("even two-digit number"); } else { System.out.println("odd two-digit number"); } } else if(num > 100 && num < 1001) { if(num % 2 == 0) { System.out.println("even three-digit number"); } else { System.out.println("odd three-digit number"); } } else { System.out.println(); } } }

useful

the code reads: line 18: Numbers between negative MAX_INTEGER_VALUE to 10, inclusive are single digit line 29: Numbers between 11 and 100, inclusive, are two digit line 40: numbers between 101 and 1000, inclusive, are three digit It should be numbers between 1-9 single digit between 10-99 two digit 100-999 three digit Also, line 53 is a violation of the condition that to not displaying anything if the number is out of range. Tip: If you look at the output line, only the first two words are interchangeable. The "-digit number" part is always the same. I would code this to figure out the what the first 2 words should be then put the pieces together in one output line:

String firstWord;
String secondWord;

{
   // in this block figure out what the first word should be: "even" or "odd"
}

{
   // in this block figure out what the second word should be: "single", "two, or "three"
}

   //output the results:
System.out.println(firstWord + " " + secondWord + "-digit number");

You already did this in your code, just in 3 times the amount of steps.
