• How can i differentiate "variable","argument","parameter"&"attribute"?


    Question:
    How can i differentiate "variable","argument","parameter"&"attribute"?

    Answers:
    this is just my understanding/usage of these terms. so no gurantee:
    all the term are variables because they are variable. A argument or a parameter are variables in a method signature/call. an attribute is a global variable aka field, property.
    But everyones understanding might differ a bit. you shouldn't worry about the exact words as long as you know how to use such things.

    A variable is mostly either a local varialbe (only used in a method) or a global variable (that can be used any where in the class).

    An arguement is a verbal disagreement that you have with someone. ;-)

    An arguement or parameter is usually used when you are passing a value or values to a method. You generally use an arugement when making a method call and the actual method uses parameters.

    An attirbute is a value that helps give a class definition. Example: A Person class could have the following attributes:
    - eye colour
    - hair colour
    - height
    - weight
