System.out.println

[Sniper-X]

i am designing a program using Blue J and for some reason i cant use System.out.println. It says it cant find the variable out, can someone PLEASE HELP!!!

[sukatoa]

how did you use the System.out.println?

If you made like System.out.println(out);
Be sure you have the out variable.

If you just want to print a word "out",

System.out.println("out");

Or, show us your code including the stackTrace( the error )

/**
* Add applicants to the system.
*/
public void addApplicant (Person newPerson)
{
if(persons.size() == capacity) {
System.out.println("All advisors are busy, please come back later." );
}
else {
persons.add(newPerson);
}
}

This is the code i used and it doesnt work can u help

[sukatoa]

This kind of error is new to me....

Just to confirm, can you show the whole error (StackTrace)?

I think printing to console is not the problem,
Just to confirm

Please post the exact error message and tell us more about what you do. Are you writing an applet? Then you don't actually have an "out".

Its either something like daniel said or you didn't install java correctly.

[rjuyal]

have u configured your Blue J correctly?

[Jesdisciple]

It's trying to use his System class. He needs to use java.lang.System.out.println().

[danielstoner]

LOL, this was funny, I didn't notice the name collision hahaha. Good catch Jesdisciple. This only proves again one should look at the problem before giving advice... and also start with the simple things first

[Jesdisciple]

Yup, that's like the programmer's lifelong struggle: Make sure it's plugged up first. (BTW, I've been getting a kick out of this, too.)
