// Printing multiple lines in a dialog box.
public class Welcome4
{
// main method begins execution of Java appliation
public static void main(String args[])
{
System.out.printf("%s\n%s\n", "Welcome to ", "Java
Programming");
} // end method main
} //end class Welcome4
It compile fine when I compile it in cmd window using javac.exe. But when
I tried it in Eclipse, it did not compile giving an exception message:
Exception in thread "main" java.lang.Error: Unresolved compilation
problem:
The method printf(String, Object[]) in the type PrintStream is not
applicable for the arguments (String, String, String)
Can anyone help?
Rgds,
Justin Loh

I know about content assist but it does not solve the problem. javac.exe
compiles OK with the same program but Eclipse just complains with the
exception message reported. Why??? The same problem is reported by Tim
Julian:
21.04. * System.out.printf Broken? Tim Julian
25.04. `* Re: System.out.printf Broken? Chris Laffra
26.04. +- Re: System.out.printf Broken? Tim Julian
26.04. `- Re: System.out.printf Broken? Tim Julian
But his case is with:
System.out.printf( "Product is %d\n", result );
It says .printf is expecting an object[] and not an int!
Eclipse did not go well with String.format method too and reports the
similar exception message.
All I know is that all these two methods are new methods in JDK1.5.0_02
version and Eclipse just don't how to deal with them (I did set the
preference>java setting to JRE1.5.0_02).

You need to be running one of the 3.1M releases of Eclipse (3.1M6 is
current) and you also need to set you compiler compliance level to 1.5.
