Thread: maintainability

Hi, I am working on a code and i need to change the code to make it easier to maintain. I have learned about re use of code so im thinking this is the way i shud be looking at the code but I cant seem to find anything to change.

the code is:

  public class Product 
 {
    /* Instance variables */ 
    public int stockLevel; 
    // The number of items of this product in stock which is updated 
    // by the deliver() and acquire() methods. Objects of other 
    // classes will need to find out its value.
 
 
public String description; 
// The name of the product which will be set to a meaningful 
// string by the constructor, and then never changed. 
// Objects of other classes will need to find out its value.
 
/** Constructor for objects of class Product
 public Product(String aDescription) 
 { 
    super(); 
    this.stockLevel = 0; 
    this.description = aDescription; 
   }
 
 /* Instance methods */
 
 /** 
  * Reduce the stock level by the value of the argument. 
  * Method presumes availability has already been checked.
  */
 
   public void deliver(int anAmount) 
   {
      this.stockLevel = this.stockLevel - anAmount; 
   }
 
 /**
* Increase the stock level by the value of the argument
*/
public void acquire(int anAmount)
{
this.stockLevel = this.stockLevel + anAmount;
}
 
/**
* Returns a string giving details of the product
*/
public String productDetails()
{
return "Product " + this.description + ": " + this.stockLevel
         + " in stock.";
} 
}what I have come up with so far is I will declare

if someone could help that wud be great.

Thanks
