Java formatted print output error

[Kirky_D]

Hello all!

I am currently learning java, just started. I have come to formatting the output of a print statement.

This is my code:


public class MathExercise2 {
public static void main(String[] args) {

double speed, distance = 5, time = 3;

speed = distance/time;

System.out.printf("The speed is %4.2f", speed);
}
}

the code compile fine, but it won't run, giving me this error:

Exception in thread "main" java.lang.NoSuchMethodError: method java.io.PrintStream.printf with signature (Ljava.lang.String;[Ljava.lang.Object;)Ljava.io.PrintStream; was not found.
at MathExercise2.main(MathExercise2.java:11)

I think that maybe i have a class library missing. Does anybody know whats going on?

Cheers all!

Your program worked fine for me here. Off hand, I would say that you are using a Java version less than 1.5 (you can check by executing 'java -version'). The printf statement only appeared in JDK 1.5.

Sorted cheers! I didn't edit /etc/jvm correctly. All is well now!
