17. Creating an object in one or two statements

• 
      // one statement
      ClassName variableName = new ClassName(argumentList);
      // two statements
      ClassName variableName;
      variableName = new ClassName(argumentList);
  
  

  For example,

  
      Product book = new Product();
      // or
      Product book;
      book = new Product();
      // or
      String code = "ISBN:123-456-7890";
      String description = "Short Novels";
      double price = 5.0;
      Product book = new Product(code, description, price);
