In Java is it possible/correct to call a method before it is declared?

Question

public static void main(String[] args) {
hello();
}
static void hello() {
System.out.println(“hi”);
}

In the example above, it looks as though the method ‘hello’ was called on the second line before it was declared two lines down.
Is it okay?

My pleasure... 👌

I think many people share the same understanding as your earlier comment and so I thought it would be helpful for me to show a simple demo. 😉

There are two such scenarios that come to mind where similar behavior can exist in Python.

First, the order doesn't matter within class methods.

Second, a similar main() function can be created to simulate a single entry point as seen in Java.

Here's a little demo I put together to demonstrate:
