Jan 15, 2017 · To reliably find all comments in a Java source file, I wouldn't use regex, but a real lexer (aka tokenizer). Two popular choices for Java are: JFlex: http://jflex.de; ANTLR: http://www.antlr.org; Contrary to popular belief, ANTLR can also be used to create only a lexer without the parser. Here's a quick ANTLR demo.

Nov 20, 2024 · In Java, there are 3 types of comments – Single Line, Multi-Line, and Documentation comments. Example: * Documentation Comments. */ 1. Single-Line Comments. A beginner-level programmer uses mostly single-line comments for describing the code functionality. It’s the easiest typed comments. Syntax: Example: 2. Multi-Line Comments.

Comments can be used to explain Java code, and to make it more readable. It can also be used to prevent execution when testing alternative code. Single-line comments start with two forward slashes (//). Any text between // and the end of the line is ignored by Java (will not be executed).

Dec 23, 2021 · Here are some rules to help you achieve a happy medium: Rule 1: Comments should not duplicate the code. Rule 2: Good comments do not excuse unclear code. Rule 3: If you can't write a clear comment, there may be a problem with the code. Rule 4: Comments should dispel confusion, not cause it. Rule 5: Explain unidiomatic code in comments.

Nov 20, 2023 · Follow these best practices to have proper comments in your application source code. Do not use unnecessary comments in the source code. If your code needs more than a normal explanation, then possibly re-factor your code.

May 30, 2009 · When you feel the need to write comments to explain what some code does, improve the readability of the code, so that comments are not needed. You can do that by renaming methods/fields/classes to have more meaningful names, and by splitting larger methods into smaller methods using the composed method pattern.

Java programs can have two kinds of comments: implementation comments and documentation comments. Implementation comments are those found in C++, which are delimited by /*...*/, and //. Documentation comments (known as "doc comments") are Java-only, and are delimited by /**...*/. Doc comments can be extracted to HTML files using the javadoc tool.

Documentation comments describe the semantics of a class, field, or method. Good documentation comments should allow you to use the class and its methods without having to read any source code. In contrast, implementation comments are used to clarify how a particular piece of code operates.

In Eclipse, put your cursor on the method name and press Ctrl + Alt + J. It will generate you a Javadoc comment with all parameters listed. You can also control the way Javadoc comment is generated in Window -> Preferences -> Java -> Code Style -> Code Templates -> Comments.

Jul 3, 2019 · You can add an unlimited number of comments to a Java file, but there are some "best practices" to follow when using comments. Generally, code comments are "implementation" comments that explain the source code , such as descriptions …
