How to write a multiline comment in java

Implementation comments are used for internal documentation. To internally document a program non-executable human-readable implementation comments are inserted.

On the other side of the alternation, mouse is not anchored, so it could match anywhere in the string—perhaps not what we intend. Java compiler does not include them in final executable.

Ultimately, this will boil down to a question of semantics. If there is an error in some code you've written, commenting out sections will prevent them from running, and can be helpful in pinpointing the source of the issue.

Comments are annotations in the source code of a program that are ignored by the interpreter, and therefore have no effect on the actual output of the code. Use lsc with no options to start REPL. For our second example, consider this string, which might represent two potential positions for placing a "submarine" on a paper grid in preparation for a naval battle: This lesson will teach you how to create two types of comments in JavaScript: Contact me at scott javadude.

Slash-star comments are the only choice when a comment needs to be inserted in middle of the code line. If you know CSS, then you're already familiar with block-level comments.

Rephrasing anchors as DIY delimiters suggests ways to implement these anchors using other meta-characters if you ever decided to write your own engine. Note that as in any alternation, the order of tokens is important: String Equivalent to LiveScript.

Creating Multi-line Comments Although a single line comment is quite useful, it can sometimes be burdensome to use when disabling long segments of code or inserting long-winded comments.

Compile a LiveScript file, creating a file. And sometimes to comment out one or more lines of code. More importantly, exploring alternate ways to perform the work of anchors brings out some of their features and suggests possible variations.

These begin with a forward slash followed by two asterisks, and end with an asterisk followed by a forward slash. The documentation generator, javadoc, will add all text inside a documentation comment to an HTML paragraph. If you are a beginner in JavaScript, you may write as much as necessary to learn and comprehend the code you write.

In fact, this is Ruby's behavior. Do not leave snippets of commented out code in your final script. How does it work. Another great thing about comments is the ability for comments to remove bits of code from execution when you are debugging your scripts.

Again there should be no white space between slash and star. Multiline All the Time There is a good argument for always leaving multiline mode on in order to give clear roles to all the anchors we've seen so far.

If we need to supply a comment somewhere in middle of the code line, then we are left with the only choice of slash-star comment. You may also use it to toggle between code to test different results. Again there should be no white space between slash and star.

Taking the time to leave proper annotation on complicated sections of code will pay dividends in the future, making it easier for you and collaborators to understand the intent of the code you have written. For example Figure 2: If you are using a specialized text editor for programming, be sure that you check and see if it has an option to easily comment out many lines of code.

You may also use documentation comments in front on non-public methods, and use a javadoc option to generate documentation for them. When working out the logic of a program, commenting out code can prove to be helpful as you determine where bugs are or assess the lines of code that offer the most utility.

These comments should be used to give overviews of code and provide additional information that is not readily available in the code itself. This lesson will teach you how to create two types of comments in JavaScript: Comments can be immensely helpful in explaining the intent of what your code is or should be doing.

It's much easier if the original code were: If you want special formatting, you must include HTML tags inside your documentation comment. String pass as string from the command line as input -d, --prelude automatically import prelude. Multi-Line (C-Style) Comments; Java also provides a comment type that can span multiple lines.

You start this type of comment with a forward slash followed by an asterisk, and end it with an asterisk followed by a forward slash. Comments are added in the code to provide information about the code you write and this makes the code easier to understand.

All professionally written codes will have sufficient comments in it to make the code easily readable and easily maintainable. Generating Javadoc Comments; References; Single-line, Multi-line and Java-doc Comments in Java Code.

Java language provides three styles (Single Line, Multi-line, and Javadoc) of comments. Before talking of a particular Java comment type we should know that a Java comment can be inserted anywhere in a program code where a white space can be.

Anchors belong to the family of regex tokens that don't match any characters, but that assert something about the string or the matching process. Anchors assert that the engine's current position in the string matches a well-determined location: for instance, the beginning of the string, or the end of a line.

Writing Comments in Java: Comments are the statements which are never executed (i.e. non-executable statements). Comments are often used to add notes between source code so that it becomes easy to understand & explain the function or operation of the corresponding part of source code.

Code line wrapping - how to handle long lines. Ask Question. We're not a Java shop, and there aren't local conventions for this sort of thing, or obviously I would simply follow them. Thanks!

java coding-style conventions line-breaks. IMHO this is the best way to write .
