How to write a comment in java

It starts with two forward slashes and continues to the end of the line. I recommend showing users information about the strength of their password as they type it, letting them decide how secure they want their password to be.

It is not clear how an attacker could use this attack to crack a password hash quicker. Explain to your users exactly how their passwords were protected—hopefully hashed with salt—and that even though they were protected with a salted hash, a malicious hacker can still run dictionary and brute force attacks on the hashes.

It's much easier if the original code were: Javadoc is a documentation tool which defines a standard format for such comments, and which can generate HTML files to view the documentation from a web broswer.

The last revision to this document was made on April 20, 5 - Comments Java programs can have two kinds of comments: First, the attacker finds strings whose hashes begin with every possible byte. Be aware that this is treated as a documentation comment even if that's not what you had intendedand could show up in the generated documentation.

If success, your Javadoc will be created in the destination folder that you had given earlier. A clever cryptographer may one day come up with a clever way to use these attacks to make cracking faster, so use HMAC. When you change the code, you change the comments, and run javadoc again.

The documentation generator, javadoc, will add all text inside a documentation comment to an HTML paragraph. These begin with a forward slash followed by two asterisks, and end with an asterisk followed by a forward slash.

No need to create proper package structure and Java source file with same name, Eclipse will take care of that. This comment is very useful especially when you write big amount of code in Java.

Error and Exception If you happen to use incorrect classes e. Only use multi-line comments to comment out sections of code. The string that takes the longest will be the one whose hash's first byte matches the real hash's first byte.

June 3 Introduction One of the nice things about Java is javadoc. Use the current password hash to ensure that they cannot do this.

If you have high security requirements, such as an encryption service would, do not let the user reset their password.

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. If not, please start using it. If a documentation comment begins with more than two asterisks, javadoc assumes this is just used to create a "box" around the comment in the source code and ignores the extra asterisks.

Often these types of comments are placed at the top of a file, or before a particularly complex code block. All professionally written codes will have sufficient comments in it to make the code easily readable and easily maintainable. Discussion of nontrivial or nonobvious design decisions is appropriate, but avoid duplicating information that is present in and clear from the code.

Exception in thread "main" org. If you have special security needs, enforce a minimum length of 12 characters and require at least two letters, two digits, and two symbols.Using the Right Comment in Java.

Java provides three types of comments: Single-Line (C++-Style) Comments 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. but if you're commenting. Javadoc comments are great. Here are several great things about them: The only person who has to look at a piece of Java code is the programmer who writes the code.

History. Javadoc was an early Java language documentation generator. Prior to the use of documentation generators it was customary to use technical writers who would typically write only standalone documentation for the software, but it was much harder to keep this documentation in sync with the software itself.

Javadoc has been used by Java since the first release, and is usually. Comments in Java Code The bold characters in the following listing are comments. /** * The HelloWorldApp class implements an application that * simply displays "Hello World!".

I want my Java application to write HTML code in a file. Right now, I am hard coding HTML tags using dominicgaudious.netedWriter class. For Example: BufferedWriter bw = new BufferedWriter(new FileWrite. Some other things you might want to know about comments in Java.

Comments do not nest. /* and */ have no special meaning in comments that begin with //. // has no special meaning in comments that begin with /* or /**. The lexical grammar implies that comments do not occur within character literals or string literals.
