define object outside the function.

[zenitis]

Hello there. I ve stuck with the next problem. I have the class SimpleDriver which include 3 functions. These functions run every milisecond. I have also a class which reads files from txt. I want to read these files in SimpleDriver but outside the functions(as i want to read the files ones). How can i make oject of the the class read_file i have outside the functions in the simpleDriver?

By saying functions I mean methods of the class.

How can i make oject of the the class read_file i have outside the functions in the simpleDriver

Define the variable that refers to the read_file object at the class level in the simpleDriver class. Ie outside of its methods.

class simpleDriver {
  read_file rdFile;  // reference to a read_file object
  void method1() {
  }
}

Ok i see what you mean. But also i want to initialize the object for example i will create an instance (read_file a;). And after that i want to open the file

a.OpenfileRead("C/.../.../..txt"); // method in class read_file that open a txt
a.rEaD(); // method that read a txt.

I can only make an object how can initialize it outside the methods of the class SimpleDriver?

how can initialize it

read_file rdFile = new read_file(); // define and assign it a value

Yea if you use constructor of the class it doesnt work it said to me "identifier expected". Basically tou can make a contructor but when you will try to make an instance of method i said before rdFile.OpenFileRead("..."); i have this message.

Ok you are right i m very clear with the problem.
I have

class SimpleDriver{
variables;
public double [][] w=null; // i want to parse the txt file into a two dimensional array

read_file rdFile = new read_file(); 
rdFile.OpenReadFile("path");
rdFile.ReaD();// read returns an array with the elements of the txt
// so here i ve tried w=rdFile.ReaD();
void methods(){
}
}

the message is cannot find symbol w identifier expected.

I didnt miss something, is exactly the message i have.

[Norm]

Only that one line? No source line number or program name?
How are you compiling your programs?

[zenitis]

I compile my files in terminal. And i have problems with these lines
rdFile.OpenReadFile("path");
rdFile.ReaD();
