I see that every time the lecturer declare a new filed, he put the 'm' letter at the beginning of the field name

Treehouse TeacherHi Faisal! There are different kinds of variables including member variables defined in a class (also called fields), variables definied in a method or code block, and variables declared in the method declarations.
The instructors here teach the convention of naming member variables as starting with the lower case "m".
Here is some documentation from Oracle about variable declaration. But note that the "m" style of naming member variables is not just a convention in Java, but other languages as well.
Hope this helps!
