Thread: help with code

I have this school assignment and I just about got it but for some reason I cannot get the continue to let me continue after I click y.

import java.util.Scanner;

public class Project4 {

/**
*
* @param args
*/
public static void main(String[] args) {

//Welcome user to the program
System.out.println ("Welcome to the factorial calculator");

int z;
double b= 1;
Scanner sc=new Scanner(System.in);

String choice = ("y");

// Get the integer
System.out.print("Enter an integer that's greater than 0 but less than 9: ");
z=sc.nextInt();

// Calculate the factorial

System.out.println("The factorial is: " +z+ ":");
for (int i=1 ; i<=z; i++){
b=b*i;
}
System.out.println(b);

//See if the user wants to continue
System.out.print("Continue? (y/n): ");
choice = sc.next();
System.out.println();

}
}

Please Edit your post and wrap your code with[code=java]<YOUR CODE HERE>[/code] to get highlighting. Your unformated code is hard to read and understand.

Where in your code do you test the value of what is read into the choice variable?
What does it mean for the code to "continue"?

I don't know how to wrap my code. and about the continue after I get my factorial for the number I put in, i need it to ask me to continue so I can put a new number in to get the factorial of a new number.

I don't know how to wrap my code.

wrap your code with
[code=java] <<<< Put this before
<YOUR CODE HERE>
[/code] <<< put this after

, i need it to ask me to continue

What does this code do?

  System.out.print("Continue? (y/n): ");
  choice = sc.next();

import java.util.Scanner;
 
public class Project4 {
 
	/**
	 * 
	 * @param args
	 */
public static void main(String[] args) {
 
//Welcome user to the program
	System.out.println ("Welcome to the factorial calculator");
 
int z;
double b= 1;
Scanner sc=new Scanner(System.in);
 
String choice = ("y");
 
// Get the integer
System.out.print("Enter an integer that's greater than 0 but less than 9: ");
z=sc.nextInt();
 
// Calculate the factorial
 
System.out.println("The factorial is: " +z+ ":");
for (int i=1 ; i<=z; i++){
b=b*i;
}
System.out.println(b);
 
//See if the user wants to continue
System.out.print("Continue? (y/n): ");
choice = sc.next();
System.out.println();
 
     }
}

Can you please give me a tip on how to add it to the program without changing anything but for it to let me continue. I tried to add a while loop and it just puts all the factorials at once and that wont work for my teacher.

You need to put the while loop around the code that does the fact computation and where you ask the user if he wants to continue. Put the question and the reading of the response inside the loop.
Exit the loop if the user does not want to stay in the loop.
For example:
while(user wants to continue)
get number
do computation
show result
ask user if he wants to continue
get user's response
end loop

thank you so very much I was able to do it.

Glad you got it working.
