static in main method in java code example
Example 1: why main method static
Because the object is not required to call the static method.
If we make the main method non-static,
JVM will have to create its object first and then call main() method which
will lead to the extra memory allocation.
Example 2: do i have to use static methods in java main
Use a static method
when you want to be able to access the method
without an instance of the class
Example 3: Static method in java
We can declare a method as static by adding keyword “static” before method name.

System.out.println("in static method.");
}
public static void main(String[] args)
{
StaticMethodExample.print();
}
}
