How can I call a method from another class?

Question

Java

There are two classes, one of which has a main method, the other class also has methods. Like me from the class. where is the main method to call methods of another class?

Answer 1

If I understand correctly, then you need to first declare the class whose method you want to call. For example like this:

class Apple{
   public String color;
   public String color(){ return color}
}
class Shop{
   public static void main(String[] args){
      Apple a = new Apple();
      System.out.println( a.color() ); // Данный метод должен вывести цвет.
}
}

And in more detail it is certainly better to read the documentation on those links that were indicated earlier.

Answer 4
