functions / subroutine 1

[stormbind]

I thought transferring skills from one programming language to another was supposed to be easy, but Java has me baffled.

My biggest problem is being unable to create a working subroutine

The code below does obviously not reflect my real objective, but pointing out all wrong assumptions would be appreciated.

public class whatever {

String global = "world";

public static void main(){
mySub("hello");
}

public static void mySub(String x){
System.out.print(x+" "+global);
}

}

2 things:
1-global has to be "static" because you use it in a static method
2-"main" needs to have "args" as an argument:

public class frmtst {

    static String global = "world";
    
    public static void main(String args[]){
        mySub("hello");
    }
    
    public static void mySub(String x){
        System.out.print(x+" "+global);
    }

}

Oh, cheers! I am home now and will try again with your input tomorrow. It had been my assumption that mistakes lay with the layout of mySub.

Thanks,

Stormbind, what language are you migrating from? When you say things like 'subroutine' instead of 'method' it tends to indicate you are coming from a non-Object Oriented language.

If this is the case, and you want to make the most out of Java, you'd be advised (at some point) to read around the subject of Object Orientation in general. Google should give you thousands of links.

No, I have used OOP languages before - it's just the small syntax differences that are throwing me
