Java Method call help!!!

joePC

Hi,

I want to call a function without passing anything down to it,

Also is it possible to call a line of code e.g. (Call 22) so it would run the code from that line.
__________________________________________________

import javax.swing.JOptionPane;

public class method {

public static void main(String[] args) {

result = two(); //Method Call two

System.out.print(result);

}
public static int two(int x){ //Method Call two

return "hello";

}

}
__________________________________________________

Thanks loads in advance....

Thanks

Ahh I see.

basically your main is in your class, but the main itself is not your class.

You have to create an object of your class before you can use the method.

eg...

method myMethod = new method;

result = myMethod.two(); //Method Call two (note to self, proofread)

Heh.. you can tell I have not had much sleep

Also you have your two() method without an argument. Which means you have to create a method without an argument for this to work or supply an int for the method you already have written.

How do I go about this?

Thanks for the reply,

Actually you don't need to have an instance of the class as the method you're trying to call is static.

All you need in main is:

method.two();

Also you're returning a string from the two method, not an int....and you're not using anythin from the JOptionPane class so you don't need the import either:

[PHP]
public class method
{
public static void main(String[] args)
{
String result = method.two(); //Method Call two
System.out.print(result);
}

public static String two() //Method Call two
{
return "hello";
}
}
[/PHP]

public static int two( int x ) {
return "hello";
}

public static int two() {
return "hello";
// or it could be...
// return this.two( 0 );
}

That won't work - as you're returning a string not and integer

joePC

Ooopss, you're right, I just copied from original post .. so, it should be ..

public static String two( int x ) {
return "hello";
}

public static String two() {
return "hello";
// or it could be...
// return this.two( 0 );
}

(Edit: but I see you've already posted the example above anyway.. Jeepers what the hell was I doing on the compose page for 6 mins
