Static keyword when used with a method, specifies that this method belongs to the class and not a particular instance of the class (a.k.a object of the class)
Ex:
public class StaticTest {
public static String getAuthorName() {
return "Anand";
}
}
Here getAuthorName is the static method and it can be accessed without instantiating an object of the class StaticTest. You can access this method as:
String authorName = StaticTest.getAuthorName();
Static java method is the same as a static variable. They belong to a class and not an object of that class. If a method needs to be in a class, but not tied to an object, then one uses static java.
Because, the main method is the starting point of the java program and if we need an object of that class even before the main can be invoked, it is not possible. Hence it is declared static so that the JVM Can acess the main method without having to instantiate that particular class
You can not overwrite a static method in Java,and 'main' is a static method.so,you can't overwrite the 'main'.
Shortly, you can not.Different approaches are however available.1. Put your non static method in different class. Then call it from your static content by first instantiating the class.2. Make a duplicate static method for your non static method and use from your static content.
In Java, the executable method is the main method, which serves as the entry point for any standalone Java application. It is defined as public static void main(String[] args), where String[] args allows for command-line arguments to be passed to the program. The main method must be declared as public and static, and it returns no value (void). When a Java program is run, the Java Virtual Machine (JVM) looks for this method to start the execution of the program.
It is uss to define class and method of pogrom's.

Yes, it is possible to call a static method from a non-static method. However, it is not possible to call a non-static method from a static method without first having an instance to operate on.
You can not overwrite a static method in Java,and 'main' is a static method.so,you can't overwrite the 'main'.
In Java, a function is called a "method". In Java as well as other languages, a method is a function defined specifically for one class. In Java, this is the only way to define functions, therefore, all functions are methods.In Java, a function is called a "method".

Static is a keyword,when u execute a method in class file loaded, execute the first this method..

in java a method is said to be static if 'static 'keyword is used before the method name . foe ex.- static void show(){ ........ } this method has the following property-- 1. it can invoke only a static method. 2. it can't be reffered using keyword 'this','super'. 3.static method can access only a STATIC MEMBER VARIABLE or STATIC CLASS VARIABLE . 4. there should not be static & non static version of a nethod in a class . 5.static method can be used before the creation of d object of dt class.
Yes you can overload the static method. But it should be avoided because memory to static methods are allocated at the time of class load.....so memory will be wasted if we don't use that methods. Whereas non-static method memory allocation depends on Object
we cannot use the staic keyword inside the method... But we can use the final keyword inside the method....
