Comments (Java and C# Cross Reference Guide)

By Mike Prestwood

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

Language Basics

Language basics is kind of a catch all for absolute beginner stuff. The items (common names) I chose for language basics is a bit random and include items like case sensitivity, commenting, declaring variables, etc.

[Other Languages]

Languages Focus

Commenting code generally has three purposes: to document your code, for psuedo coding prior to coding, and to embed compiler directives. Most languages support both a single line comment and a multiple line comment. Some languages also use comments to give instructions to the compiler or interpreter.

Java: // or /* ... */

Commenting Code
Java uses "//" for a single line comment and /* */ for a multiple line comment.

Syntax Example:

//Single line comment in MS (not ANSI compliant so do NOT use).
/* ANSI compliant single line comment. */
/*
Multiple line
comment.

*/

/*

* This is another popular way

* to write multi-line comments.

*/

C#: "Multiple Line Comment" // or /* */

Commenting Code
C# uses "//" for a single line comment and /* */ for a multiple line comment.

Syntax Example:

//Single line comment.

/*
Multiple line
comment.

*/
