How to add javaDoc to Java code in a NetBeans based project?

Question

How can I add a JavaDoc or other document to netbeans?
I try this way:

Tools >> Java Platform >> JavaDoc Tab >> JavaDoc.zip (in my desktop) 

but in the editor, when I press Ctrl + Space in tooltiptext, this message is shown:

Javadok not found. The Javadoc documentation for this item does not exist or you did not add the specified Javadoc in the Java Platform Manager or in the Library Manager.

I tried restarting NetBeans, but this was the result:

Answer 1

try this in NetBeans IDE

• In the main window, select Tools> Java Platform Manager.
• Select the platform on which you want to add Javadoc to the left pane of the dialog box.
• On the Javadoc tab, click Add ZIP / Folder and specify the location of the Javadoc files.
• Click "Close."

Hope this helps.

Answer 2

Usually you can’t just add javadoc zip as a separate library (at least this has not worked for me in the past). In the "Library" section, you need to select the library to which you want to add Javadoc for and then add the Javadoc jar for this particular library.

Restart Netbeans, after which it should work. Although, of course, if there is no Javadoc on this method, you still won’t get it (I fell into this trap a couple of times earlier!)

Answer 3

You followed the most correct procedure, I threw it right before writing this answer, and since this is the first result that appears when you encounter a Google problem, I think it will be convenient for many people and save your time, solutions :

UNZIP is the JavaDoc.zip file that you are referencing (which should be jdk-7u4-apidocs.zip for JavaSE 7 documents) and repeat the same procedure as Tools → Java Platforms → Javadoc (tab), then click "Add mail index / folder "and point to the unpacked folder instead of the jammed one, restart NetBeans, and it will work smoothly and directly.

You should download the docs file from the following link: http://www.oracle.com/technetwork/java/javase/documentation/java-se-7-doc-download-435117.html

After completing the described operation, your javadocs will not be available for you, and you do not need to connect to the Internet to find out about the API.

Best regards, brother.

I had the same problem and solved it by removing all the urls and adding only apidocs.zip downloaded from oracle. After that, restart NetBeans.

Before checking if it works, make sure that the method you are looking for really exists in apidocs. Open index.html and search for exactly this package.class.method .

If this does not work, try manually copying apidoc.zip to the docs netBeans directory: C: \ Program Files \ NetBeans 7.1.2 \ java \ docs and try again.

Answer 6

" Tools → Java Platform → JavaDoc Tab → JavaDoc.zip "

The problem with the above step can be easily solved by moving down two paths already added to the content panel, as shown below.

Step 1 -

• Go to: Tools → Java Platform → JavaDoc Tab and add the zip / folder you want to add.

Step 2 -

• 

Step 3 -

• 

That is all, and if the zip file does not extract first, then adds it.

Answer 7

This worked for me, I will manually copy apidoc.zip to the netBeans docs directory: C: \ Program Files \ NetBeans 7.1.2 \ java \ docs, and then restart my netbeans.

Answer 8

Using the Maven project inside Netbeans v8.02.

First view your project through the Projects window;

• Expand the project dependencies folder
• Right-click the desired * .jar file.
• Click javadoc download button

Done!

Answer 9

If you are using maven in your project, follow these steps to add Java documents for your nested libraries.

• Right-click the Dependencies folder for your project.
• Then select the option "Download javadoc"
• It will download the javadoc of your libraries and attach it.
• Now when you press ctl + space, you will see the documents for this library.

and if you want to add javadoc for a specific library, then follow the options suggested by Himanshu Soni.
