Hi,

I do have a very basic java question.

I have the following class :

public class IntTest
{

public static void main(String[] args)
{
Integer i = 100;
Integer i2 = 100;
System.out.println((i == i2)? "Yes equal": "Nope not equal");

}
}

I want to compile this class on a win2000 system with jdk 1.5 installed.
java -version gives me :
java version "1.5.0_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_01-b08)
Java HotSpot(TM) Client VM (build 1.5.0_01-b08, mixed mode, sharing)

If I'm correct : I want to compile this. because I use autoboxing I have to compile this using the -source 1.5 flag.

If I do : javac -source 1.5 IntTest.java
I get :
javac: invalid flag: -source
Usage: javac <options> <source files>
where possible options include:......... etc.
In the list with possible options it does not state : source

What am I doing wrong?

Kind regards
Werner

It tells me that you can't do javac - version.

javac: invalid flag: -version
Usage: javac <options> <source files>
where possible options include:.......

Funny, I get this:I would have expected the -version flag to have existed in 1.0, but maybe it's not and you have an ancient JDK on your system. Does your path include multiple JDKs?
 
Don't get me started about those stupid light bulbs.
