string.equals("");

[Timos Mann]

Hey guys. Im sorry if my question will be a little vague and "noob" but i have this problem ive been thinking for 2 hours and im tired,i hope maybe you can help again.
I read a string from the keyboard and i use an if to determine what "word" is it. The if (xx.equals("exit"){ seems to be working fine,but the other two don't.Its so simple i cant think whats going wrong...

public void go() {
			String temp;
			
			while (com==false) {
				temp="";
				temp=reader.getUserInput("Enter 'knot' for conversion to knots,or 'B' for conversion to Beaufor.\n Enter 'exit' to exit program.");
				if (temp.equals("knot")) {
					System.out.println(this.getKnot(kphSpeed));
				}
				else if (temp.equals("B")) {
					System.out.print("checking");
					int x=this.getB(kphSpeed);
					System.out.println(x);
				}
				else if (temp.equals("exit")) {
					com=true;
				}
				else { System.out.println("Invalid Input-+-+-+-+");
				}
			}
		}

It would help if you described what "don't seem to be working fine" actually means in your environment.

Thanks for fast reply Paul. Well,im not sure i understand your question,but i mean that, what i wanted to do,is read a string, then say if the string is "B" call the getB method(), if it is "knot" the getKnot method,if it is "exit" make the com true so you exit the loop. So if i enter "exit" it leaves the loop,but entering B or knot doesnt work,its like entering wrong text,back to loop start. I dont know if that was your question.

So you get the invalid input message? How about printing what that invalid input is:

else { System.out.println("Invalid Input-+-+-+-+" + temp + "+-+-+-+");

you were right,i should have seen it. i forgot an (int) in the methods within the if... geez. Thanks Paul, i was totaly stuck

What he means is TellTheDetails. Your original post said (basically) "this case doesn't work". That doesn't tell us much. does the program choke and die? Does it run the wrong block? Does it run the right block but the code in that block is wrong?

the more info you give people, the easier it is for them to help, and the more likely they will help.

Yes,im sorry Fred you are right. Im just kind of new to java,plus i was really tired. After finding what was wrong i can say for sure there was no way to get help the way i asked it. Thanks for taking the time to answer my thread though!

Never say while (com==false) . . . It's while (!com) . . .

Did you sort your problem out? What did you do? Your last posting leaves us even more confused about what is happening.
