I have tried to use java printf (available in jdk1.5.0_02) in the
following program:
//Fig 2.6: Welcome4.java
// 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

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.
