About static method in java

Question

I know mean of static and know that
If we have static method
variable inside this method must be static
as variable is copying
But question
What about method not static inside method static
Why i can't make this

Answer 1

Suppose you have a class and you haven't created any object yet.

This will help you realise how calling instance variables or instance methods will not work in a static context.

Answer 2

Declaring a variable inside a static method does not require the keyword static.

"method not static inside method static "
You can't declare method direct inside method.
If you mean how to call non-static field you must create object first.

public class Program {
int nonStatic;

public static void main(String[] args) { //static method
new Program().main2();} void main2(){
nonStatic=20; //non static method
nonStatic();
}
void nonStatic() {
}
}
