This is to add on noob developer comments.
A program needs a place to start its execution; for Java programs we need include the main method inside a class for the program to work.
When the JVM (read as Java's Interpreter for now) executes an application, it first starts by finding and calling the main method() . The main method then calls all the other methods required to run your Java application.
Just note that main method is typed beginning with a small m and its signature i.e. public static void main(String[] args) {} has to be typed exactly like that with no alterations to avoid errors.
Generally Java method names begin with a Small letter while Java classes begin with a Capital Letter. The methods have to be inside a Class and that includes the main () method.
