Creating a function

[girldemsuga]

Im new to java and was just trying out the language.
Im using Net Beans and started a new project. the Main class and function was automatically created for me.
I then tried to write some additional functions which i would call from the main class.
No matter what I do, I am unable to call these user created functions in the main class. I did some googling for examples and tutorials and noticed that they always created the user functions in another class.

I which case, I would have to create an instance of that class then call the function.
Is that how it is done is Java or am I doing something wrong?

paste some code. one of the things that i noticed with java is that i had to initialize an object before i could use it.
i did that with new

package helloworldapp;

/**
 *
 * The HelloWorldApp class implements an application that
 * simply prints "Hello World!" to standard output.
 *
 * @author wiel
 */
public class HelloWorldApp {

    /**
     * @param args the command line arguments
     */
    public void prnt(){
     System.out.println("Hello World!");
    }
    public static void main(String[] args) {
       HelloWorldApp a;
       a=new HelloWorldApp();

        a.prnt();// Display the string
    }

}

What you did was to create an instance on the class within itself.
I must say that am a bit disappointed in Java if that is how it is done, or it just case were i have to get use to it.

my experience is based on C#, C++ and php.

By the way wiel, thanks for your help.

no problem. its not a safe practice to go around declaring global functions all the time. maybe thats why they threw that out the window
