compile error - calling methods from main

[counterfox]

Hi all doing college question again but stuck right at the end of it >.< pretty much is a simple program to just check if two command line arguements have been made, otherwise it just prints the last command line arguement (from args[1]) The only problem I have with this is that theres already a print method made which you have to use to output args[1] so you cant simply use System.out.println()

Heres the code:

public class Exercise {
public void printout(String a) { //Not allowed to change
System.out.println(a); //Not allowed to change
} //Not allowed to change

public static void main(String args[]) {

int arraysize = args.length;
String output = "";

if(arraysize>2) {
output = "Wrong input";
}
else if(arraysize<2) {
output = "Wrong input";
} //End if
else {
output = args[1];
}

printout(output);



}
}

the problem is the last line when i try to call printout() it gives a complile error like non-static method can be referenced from a static context. And because the question your not allowed to change that method at all.

Thanks in advance

yeah, the compiler has a point.

as a quick fix, do this:

public static void main (String[] args) {
  (new Exercise()).doStuff (args);
}
public void doStuff (String[] args) {
  //copy-paste in here whatever's in your main() now
}

but you really should read up on what "static" actually means...
