Getting error when compiling with printf

[Ivan]

Hi all..

I'm getting an error when trying to compile an adaptation of my
HelloWorld program..

The code looks something like this:

System.out.printf( "%s\n%s\n",
"Hello", "World!" );

I read somewhere that printf is a new feature of J2SE 5.0, so I
reluctenty upgraded from 1.4.2 to 1.5.0, though I'm still getting the
error..

I'll post the error if required, but it's on the other computer..

The code works fine for me.

It's very poor form to ask for advice on "an error message" without at
least making some attempt to characterize what sort of error message you
mean.

It's pretty much required. The posted code, placed in a class's public
static void main (String[]) method, works fine for me.

I know.. Was just a bit hard being that it was on my other computer..
But, here it is:

public class Hello
{
public static void main ( String args [] )
{
System.out.printf( "%s\n%s\n,
"Hello", "World!" );
}
}

$ javac Hello.java
Hello.java:5: cannot resolve symbol
symbol : method printf
(java.long.String,java.lang.String,java.lang.String)
location : class java.io.PrintStream
System.out.printf( %s\n%s\n",
^

Type javac -version to see if you're really using 5.0.

If so, type echo %CLASSPATH% or echo $CLASSPATH to see if you got the
rt.jar of an older jdk in the classpath.

If not, type echo %PATH% or echo $PATH to see where the OS gets the
javac executable.

$ javac Hello.java
Hello.java:5: cannot resolve symbol
symbol : method printf
(java.long.String,java.lang.String,java.lang.String)
location : class java.io.PrintStream
System.out.printf( %s\n%s\n",

One problem is your " don't balance.

that method was just invented with JDK 1.5. Are you using an older
Java?

See http://mindprod.com/jgloss/jdk.html
to upgrade.

Got it working.. Thanks.
I was using 1.4.2 (even though I installed 5.0, I was still using javac
from 1.4.2).
