Thread: class assignment

Hi shanem and welcome.

There is a sticky posted at the top of this section you should read, here is a link:
This Forum is for Saying Hi, not for Asking Technical Questions (READ BEFORE POSTING)


Also please see the Announcements (aka forum rules, but rules makes it sound so restrictive).


What is the first step taught in your class? -What are you stuck on?

What have you done so far? -Always post related code and error messages with your question.

You said nothing about what kind of numbers to accept or reject from the user input.

If you want to find unique numbers of a set you would have to have some way to remember what numbers you have already seen as you go. How could you remember the numbers the user has input as you go?

When comparing your strings, what is the trouble? Is there an error? Does it compile and run but give unexpected/undesired results? Are you using == to compare? Questions like this could be answered if you included your code.

Good luck with your assignment. If you have any more questions please try to as a well formed question about the problem you have and don't forget to include your code/error messages.




Thread moved from member introductions.

hi i want to take in a integer from the user and use a boolean true or false to find out if each number is unique?? i know how to take in the number and convert it to a string but having trouble setting conditional to compare each character. I thought you could compare each element of the string to the other element but am not sure how to do thisThis what i have so far I am only doing java 3 weeks .
import java.util.Scanner;

public class Numberunique
{
public static void main ( String args[] )
{

int userInput = 0;
boolean unique = false;
String myString = "";



Scanner input = new Scanner( System.in );
System.out.println (" enter your number");
userInput = input.nextInt();

myString = Integer.toString(userInput);

for ( int i = 0; i <= myString.length (); i ++)
{
if ( myString. charAt(0) == myString.charAt(1))

unique = false;

}
System.out.println( "the number entered " + unique );
}




}

yes , i want to do this using a nested loop

i figured it out earlier i just need a nested for loop but thanks for all the help NOT
