Is there a good way to keep track of argument variables passed into classes

Question

public class Tester {

   private double length;
   private double width;
   private double height;

   public Tester(double ________1, double _________2, double _________3){

      length = _________1
      width =  _________2
      height = _________3

   }//Tester constructor
}//Tester class

Above is a simple sample code and I was wondering if there is a "good" naming convention for naming variables when making classes?

For example what would be good names for _____1, _____2, _____3?

Would it be something like testerLength, testerWidth, testerHeight?

Answer 1

The names of the arguments should be very meaningful, because you will see them in the Javadoc. You have multiple options here, I will give you an example for a few:

an a before every argument:

public Tester(double aLength, double aWidth, double aHeight) {
    length = aLength;
    width = aWidth;
    height = aHeight;
}

as @Cyber mentioned: using an _:

public Tester(double length, double _width, double _height) {
    length = _length;
    width = _width;
    height = _height;
}

and my personal favorite, just use the same name and the scope:

public Tester(double length, double width, double height) {
    this.length = length;
    this.width = width;
    this.height = height;
}
