Basically I am to create a program that does the following.

Prompt a user to input a 5 digit value.

When the user inputs a value such as 12345 and hits enter

the program should put tabs inbetween each individual digit

such as 1 2 3 4 5

I cannot find this out for the life of me......heres sort of what I have I know its wrong but if someone could please edit my code and bold what they've changed I WOULD APPRECIATE IT!!

heres the only encouragement my teacher has provided...

There are two ways to do it, either treat user input as string and use substring method to get individual digits.

Other way is to treat user input as a number, and perform division and remainder operations on it to get required digits

Heres is my code

Code:

``` //******************************************************************** //  Five.java      Author: //  Program breaks apart a five-digit number. //******************************************************************** package assignment2; import java.util.Scanner; public class Five {     //-----------------------------------------------------------------     //  Prompts user to enter a five-digit number then outputs tab spaces between each digit.     //-----------------------------------------------------------------         public static void main( String args[] )         {                 String digits;                                 Scanner scan = new Scanner (System.in);                                 System.out.print ("Please enter a five digit number: ");                           digits = scan.nextLine();                                 System.out.println (n1+ "\t" + n2+ "\t" + n3+ "\t" n4+ "\t"n5+ "\t");                                         } // end main } // end class Five```

this should help you to get going

Code:

```                String digits;                 Scanner scan = new Scanner (System.in);                 System.out.print ("Please enter a five digit number: ");                 digits = scan.nextLine();         String n1 = digits.substring(0,1) ;         String n2 = digits.substring(1,2) ;         System.out.println (n1+ "\t" + n2+ "\t" );```
the parameters for substring can be confusing at first. The first parameter is the index of the string that you want to start from, the second parameter is the end index and the string will be substringed up to the endindex -1, or another way of looking at it. The first parameter is the index of the string that you want to start from, and the second parameter - the first parameter gives the length of the substring

Since you number is in a string, the most simple way is use the charAt() as follows.

Code:

`System.out.println(digits.charAt(0)); // First digit`
