Question

i am trying to understand why this won’t run. I am thinking that I may need to import a package. I would also like to know what happens in the class LocalVariables on the the line myObject.f();

I think that I have just instantiated myObject on the previous line but am I calling the f method with myObject.f(); ????? I don’t understand what is supposed to happen on that line.
Any help would be appreciated.

class MyObject{
 static short s = 400; //static variable
 int i = 200;  //instance variable

 void f() {
     System.out.println("s = " + s);
     System.out.println("i = " + i);
     short s = 300;  //local variable
     int i = 100;  //local variable
     double d = 1E100;  //local variable
     System.out.println("s = "+s);
     System.out.println("i = " +i);
     System.out.println("d = " + d);
          }
     }


class LocalVariables{
    public static void main(String[] args){
        MyObject myObject = new MyObject();
        myObject.f();
    }
}

change void f() to public void f() { //Code... }
