To call a method in java, write the method name followed by a set of parentheses (), followed by a semicolon (;). a class must have a matching filename (main and main.java). like we specified in the classes chapter, it is a good practice to create an object of a class and access it in another class. All methods and constructors in java have some access modifier. the main () method also needs one. there is no reason why it should not be public, and be any other modifier (default protected private). notice that if we do not make main () method public, there is no compilation error.
