execute non-static method in main()
hi,
i'd encounter a serious problem and urgently need to know how to solve this problem. for simplicity the problem i use the following illustration.
class testing
{
void test()
{
System.out.println( "1234" );
}
public static void main( String[] args )
{
test();
}
}
when i compile this file, it return following error message:
non-static method test() cannot be reference from a static context...
how to solve this problem ? anybody have any idea or suggestion? in my case, i have to use some non-static methods( form other classes ) in the main() ~~@_@~~

Trying to remain as congnial as possible, your first advice is very good and concise. Perhaps the clearest answer that I had read (because it's so simple) on this problem, which according to a few people is one of the most typical problems encountered by people new to java.
Which is why your advice "And read the tutorials. " is so frustrating to read.
http://developer.java.sun.com/developer/onlineTraining/ has a lot of tutorials on a lot of subjects, and frankly this doesn't seem to be covered as such in any of them via a cursory glance.
This doesn't mean that you shouldnt recommend the tutorials. I would suggest only that you recommend reading a specific section of a specific tutorial.
Not as easy as saying "And read the tutorials," but certainly more helpful.

Just make it this:class testing {
// this needs to be a static method for main() to access it
static void test() {
System.out.println("1234");
}
public static void main(String[] args) {
test();
}
}
