Member Method (Java and C# Cross Reference Guide)

By Mike Prestwood

Java versus C#: A side by side comparison between Java and C#.

OOP Basics

Some languages support object-based concepts such as Paradox, Access, and VB Classic. Other languages have OO extensions and fully support object orientation in a hybrid fashion (such as C++ and Dephi for Win32). Finally, some lanages such as C#, VB.Net, Prism, and Java are entirely written in OO. Meaning, every line of code written must occur within a class).

Member Method

[Other Languages]

Also known as a Class Method.

A code routine that belongs to the class or an object instance (an instance of the class). Methods that belong to the class are called class methods or static methods. Methods that belong to an object instance are called instance methods, or simply methods.

When a method returns a value, it is a function method. When no value is returned (or void), it is a procedure method.

Methods frequently use method parameters to transfer data. When one object instance calls another object instance using a method with parameters, you call that messaging.

C#:

In C#, you indicate a method with parens, no parens indicates a member property. Use the void return type for methods that do not return a value.

Syntax Example:

Define class:

public class Cyborg : System.Object
{
  public virtual void IntroduceYourself()
  {
    MessageBox.Show("Hi, I do not have a name yet.");  
  }
}

Create object from class:

Cyborg T1 = new Cyborg();
T1.IntroduceYourself();
