package com.sudhirtheindian2.java123;

 class syntax_of_java {
    public static void main(String[] arg) {
        System.out.println("hi");


//        1-  create a class and provide name
//            example- syntax_of_java is class name



//         2-   { open curley bracket


//         3-} close culey bracket


//        4 class has method, here main is method name
//        main method - program execution start from here and end

//        starting and ending point of the program is main method


//       5  why main method is public ?
//        jvm(java virtual machine) run the program outside so
//                main method is public
//        if main method is not public then jvm can not run the program



//        6 why main method is static ?

//        without making object of this class
//                we can execute code written in main method

//        7 why main method is void ?
//        there is no requirement to return anything


//       8   main(String[] args)
//        if we pass anything in main method that is known parameter
//        this is also known as command line arguments

//       9  here String is predefined class
//          the name of class start with capital letter
//        string is also use as a datatype in java


//        10
//        args
//        here args is array variable

    }
