1. Are there ways to make it easier to keep track of what a section of code does?

2.Lets say I have a class to keep track of the objects in my kitchen. Each object has a height that I want to keep track of. It doesn't make sense to have a negative height, so I want to make sure that each object has a positive height. How can setters make sure that this is true?

3.In some ways any program that runs correctly is good, but there are good practices to follow when writing code. What are they?

Explanation / Answer

       }
   }
}

class track
{
   public static void main(String args[])
   {
       a o=new a(5);
       a o = new a(-4);
