In this part of the Java Tutorial, I will talk about methods and their return statements. Let's start with the really basics:
The public static void main(String[] args){ }
code, where you write all your code that will be executed, is actually a method. The method got the following attributes, it is public, it is static, it is called main, you can give it a string list of arguments called args.
So lets keep this format and change some parts, let's change name main to myMethod and remove the (String[] args)
part and just let the braces empty ()
. Now our method looks like this:
public static void myMethod(){ }
(Of course it shouldn't stand in the main method. Write it under your main method)
And now lets give this method some code, like
public static void myMethod(){
System.out.println("I'm called from a method!");
}
Now write in your main method just the name of your method with empty braces at the end and then run the code -> myMethod();
Our code should look like this:
public class Main{
public static void main(String[] args){
myMethod();
}
public static void myMethod(){
System.out.println("I'm called from a method!");
}
}
Now run this and the output should be "I'm called from a method!"

Remember: I'm not a genius too! I'm 16 years old but I know quite a lot, because Java or programming in general is fascinating me so much (and yes I have friends and other hobbies :)). So don't give up! Follow you dreams and in some day, they will get true.
