I'm taking Java for a spin, and have ran into a problem with my first app. Here's the code...

class Displayer
{
public static void main(String args[])
{
System.out.printIn( "Hello world!" );
}
}



This is the error JJEdit is giving...

First App.java:5: cannot resolve symbol
symbol : method printIn (java.lang.String)
location: class java.io.PrintStream
System.out.printIn( "You'll love Java!!!" );
^
1 error


So what's the problem? Any ideas?

It's println as in "printLn"

When ever you get the message in an error message that says:

cannot resolve symbol

It usually means that you have miss spelled a method or class/object name incorrectly.

Also try to use a more standard Java formating like this.

class Displayer {
public static void main(String args[]) {
System.out.println( "Hello world!" );
}
}


See the Java Sun site for details. It just helps you and other Java programmers read your code.

Best luck - Coding

actually, it's none of the above...

the problem is with the arguments that you're passing to main().

it should be:

public static void main(String[] args) {...}

...it's "String[]" meaning that you're passing an array of Strings called "args"...

that should fix you're problem.

ps it's "System.out.println" not "printLn"

Noooo.... You can use String args[] also, it is equivalent in Java.

The problem is that he's calling System.out.printIn, with a capital i instead of a lower case L... I used to have these problems with javadocs too, they use a font that doesn't differentiate between uppercase i and lowercase L very easily...

By George, you're right! I looked at this for awhile without seeing it. I was starting to think my Java skills were pretty weak.

Apparently they are - whenever the compiler complains about a method or constructor or class name not found that should clue you in that that is the problem. Now if you have a syntax error, those can be pretty hard to find since the compiler will start spewing out all kinds of weird errors.
