Hi again all,
Is there anyway you can compare two things in a .equals statement.
For example.
If(symptoms.equals("headache" ||"head hurts"))
{
System.out.println"BLah blah blah");
}
I tried that but it gives a weird error so i was wondering is there ANOTHER method i need to combine to make that to work?
MS
> if(symptoms.equals("...") ||
> symptoms.equals("...."))
It works, but once again i'm having a trouble with the loop.
If you try this code it works fine but when it asks if you would like to try again and you hit "y" it just skips to the else statement.
Here it is:
import java.util.*;
import java.text.*;
public class Medicine
{
public static void main(String[]args)
{
String symptom, answer;
Scanner scan=new Scanner(System.in);
do{
System.out.println("Please enter the symptom(s) you are experiencing:");
symptom=scan.nextLine();
System.out.println();
System.out.println();
if(symptom.equalsIgnoreCase("I have a headache") ||(symptom.equalsIgnoreCase("My head hurts" )))
{
System.out.println("You need tylenol or asprin");
}
else
System.out.println("I'm sorry i did not find any medicine which will meed your symptom");
System.out.println("Would you like to try again?");
answer=scan.next();
}while(answer.equalsIgnoreCase("y"));
}
}
Any ideas of why it would do that?
Thanks MS

For some reason there is a bug with Jgrasp of when you put next line it doesn't execute it.
Captain Morgan found that out for me last time i posted somethign with a loop.
Try it for yourself, it skips the NextLine, but executes on NExt.
I asked my professor he said it might be a bug.
Ty, any other ideas?

It igves an error saying:
; expected after while statement. Heres the code i changed.
System.out.println("Would you like to try again?");
answer=scan.nextLine();
}while(answer.toLowerCase().charAt(0) == 'y'));
}

Wow tried it with line and it actually worked this time.
Nice man, but wierd. here it is.
do{
System.out.println("Please enter the symptom(s) you are experiencing:");
symptom=scan.nextLine();
System.out.println();
System.out.println();
if(symptom.equalsIgnoreCase("I have a headache") ||(symptom.equalsIgnoreCase("My head hurts" )))
{
System.out.println("You need tylenol or asprin");
}
else
System.out.println("I'm sorry i did not find any medicine which will meed your symptom");
System.out.println("Would you like to try again?");
answer=scan.nextLine();
}while(answer.equalsIgnoreCase("y"));
}
Ty all I'm sure i'll be back with another question shortly.

Like I said, read through your old thread to see the difference between next() and nextLine().
http://forum.java.sun.com/thread.jspa?threadID=792181&messageID=4502353#4502353
nextLine() reads the whole line while next() only reads the next token.
