Hi Klaudia.
Just as Shane said, objects are very important concepts in Java. We create a new Object in java with the "new" Keyword. This is used to invokes a new Constructor Object like this... Dog dog = new Dog(); . Here "dog" becomes a new reference variable, which can be used to call any method in the Constructor class like this dog.buck(); . Assuming buck is a method in the Dog class.
The example you have above is public static void main(String[] args) {} is called when you want to execute a java program.
Public means main() method can be called from everywhere
Static means main does not belong to a specific object 
void means main does not return a value 
Main() is a special function that is used to start a program.
String[] is an array of arrays
That said you can not create a new Object from a static method. You can only create a new Object from a non static or non Final class, an instance method, and so on.
Some Access Modifiers and the Final Keyword prevents new Objects from being created. You can find more help on stack overflow http://stackoverflow.com/questions/2350552/creating-objects-in-java-question

Java objects are a very important concept to understand, I would recommend going back and re-watching the videos to get a better grasp of it. Also, go Googling to get a deeper understanding, if necessary, there are many tutorials like this one (http://www.tutorialspoint.com/java/java_object_classes.htm) that could help you with your understanding.
