The object referred to by the reference variable w has its own copy of size, color, and capacity If we were to create a new wheel (Wheel w1 = new Wheel();), it would also have its own copy of size, color, and capacity Suppose, though, that you have to keep some data about a wheel that is universal and constant for every wheel created It would be a waste of space and time to create this information for every instance of a wheel Instead we would declare the property with the modifier static in order to tell the compiler that the data belongs to the class and not to the object In order to access class data, you use the class name and not the reference variable Consider our class file Converter Instead of using the number 32 in the code, we could create static data that represents the number This is similar to creating global constants in other programming languages In the Converter class, we would add a line in the variable declarations that states:

In order to access this variable, we would code Converterdifference since the data does not belong to any one particular instance of the Converter class There is a difference here between the constants of other languages and this manner of creating static data: In another language, you would not be able to change the value of difference because it is a constant (non-changeable) In C#, you are able to change the value because it is a variable, not a constant If any changes are made to difference, all other access to the variable (as long as the class is loaded in memory) will reflect the change See 4 for a detailed description of the class loader and memory locations NOTE If you are a Visual Basic programmer, the concept of a static variable is quite different Static, in VB, means simply, that the variable s value is retained between method calls In C#, it means that the data belongs to the class and not to the object

Then we call solve to nd the roots:

The static modifier can be applied to methods as well as properties As a matter of fact, we have been doing just that throughout this chapter Every time we create a class file, we have included this line:

public static void Main()

the damaged tires with new Toughgrip tires A Toughgrip tires are the only tires the driver can afford B The driver feels obligated to buy tires from his brother, who sells only Toughgrip tires C One of the tires was slashed by a rival driver, while the other two blew out in traffic because of material defects D The Toughgrip Company offered to replace all of the tires free of charge because the tires were covered under a 60,000-mile warranty E The taxi company for which the driver works has endorsed Toughgrip as the official tire of their company s cars

By placing static in the signature of the method, you are asking the compiler to consider the method as belonging to the class and not to an instance of the class (an object) When an application that contains the class is loaded, all static methods are loaded as part of the class That is why the Main() method must be declared as static in order for it to be executed, it cannot be a method that belongs to an object because those methods are only called by sending a message to the object Class methods (or static methods) are executed independently without the assistance of an object

The following two questions are based on the following passage:

So that explains why Main() is static, but why else would you create static methods Consider utility functions like our Convert() method It is possible to place this method in a class that simply defines static, utility methods as follows:

public static int convertValue = 32;
