Java Strings (need help, won't take long at all for those who know what they are doing)

[renaissance]

Here is my code:



c.print ("Are you male or female (m/f)? ");
gender = c.readLine ();
while (true)
{
if (!(gender.equals (male)) || !(gender.equals (female)))
{
c.println ("Please enter 'm' if you are male, or 'f' if you are female.");
gender = c.readString ();
}
else
break;
}



I am asking the user to enter "m" if they are male and "f" if they are female. I want to compare the string they enter with the characters "m" and "f" to make sure they entered on of those characters. Will someone explain how to do this? Thanks.

I know this code will achieve what I want...but how do I do it with the format above?




c.print ("Are you male or female (m/f)? ");
gender = c.readLine ();
while (true)
{
if (gender.equals ("m") || gender.equals ("f"))
break;
else
{
c.println ("Please enter 'm' if you are male, or 'f' if you are female.");
gender = c.readString ();
}
}

What will the following do?

code:

String var = "a"; if (var.equals("a")) {      System.out.println("Yes"); } else {      System.out.println("No"); }

If you understand that small piece of code, you should understand what to do to solve your problem.

Edit: Ugh my Java skills are getting rusty.

Just a general point: never use breaks horrible way to program.

What about when you want to prevent a fall through with a switch structure? Breaks are pretty useful then.

Then use a better language?

umm. did anyone else notice that said individual who started this thread is NOT using regular java? They are using Ready to Program by Holtsoft. just thought i'd throw that out there. the code will still work for him, but if you try to compile it using anything else, you get errors galore. Holtsoft programs suck.

edit: if you try to compile rennisence code you get an error.

So just change 'c' into "System.out" The logic still applies.

[S_Grimm]

I know. just pointing it out for anyone else who reads this and trys to compile it.

Hmm...well...I figured out an alternative...so all is working . Didn't realize that using Holtsoft's Ready To Program program would be that bad :i...oh well...that's what I'm stuck with for my course so I'll just have to learn it Thanks for everyone's help...and side conversations ^.^ rather entertaining.

[S_Grimm]

when you do program with Ready, avoid the Console C stuff. use System.out.print or System.out.println
there universal.

edit: Sorry, forgot to capitalize the System.out

Please no. Mindless copying and pasting of code so that the program "just works" is the path to the dark side.

Understand the code you're writing.
