It's a phrase that makes sure that the method is class level. You don't need to create an instance of the class in order to access static members.
The public static void geek is a class of static methods.
It's perfectly OK if you have a static public void instead of a static public void. Your program will run successfully. As long as method name comes last and return type comes last, it doesn't really make a difference.
Why Main is static in Java?
The main is static. It can be directly invoked via the class since it is static.
When a class is loaded, the static method and static data are loaded into separate memory inside the JVM, which is called context. If the main method is static, it will be loaded in the context of the JVM and available for execution.
In the case of core java applications, the main method is referred to as the entry point. The main method in Java is run by the main thread which is a non-daemon thread.

What is difference between static and constant in Java?
Constant is a fixed value that does not change during the execution of a program. The program shows the value of constants. Another name of constant is literals. The constants are used to assign values to variables. Constants make our program easy to understand by others. They are declared in a class.
In a sample function, the code is executed in a first call of the function, but not in a subsequent call, because of the static variable. The code has a constant value for a constant variable. You can set the constant variable like that.
You can have multiple static variables in different c++ source code files with the const means constant.
It is possible to make a variable a class variable. While declaring, you don't need to define a static variable.
There is a variable. The variable can change the value.

What is static and final in Java?
The value is the same for every instance of the class. Once the variable is assigned a value, it can never be changed. A constant value can be created with the combination of static final and Java.
Square is a static method in the above program. The value is an integer. The static method is used in the main method. The variable result stores the answer from the method. The class name is used to access the static method.
The static methods can't use non-static data members or call non-static methods directly. If you assess a non-static variable by a static method, it will give you a time error. There is a big difference between static and final methods.
There is no such thing as a top-level static class in Java.
A blank final instance variable of a class must be assigned at the end of every constructor of the class in which it is declared; similarly, a blank final static variable must be assigned in a static initializer of the class in which it is declared.
static class, static variables, and static Class are supported by C# C#. C#. Java supports static methods and variables.
