Eclipse doesn't find javax.swing

Question

Eclipse cant find the import javax.swing.JOptionPane

Where is it located and how can i include it?

import javax.swing.JOptionPane;

It's included in the JDK. Post your code and the exact error message. Tell us what you have in your build path. — JB Nizet, Jan 06 '13 at 10:19
import statement is correct. which version of eclipse you using and what type of project you have chose while creating new project? — exexzian, Jan 06 '13 at 10:21
Christian, what version of Eclipse are you using? One of those from eclipse.org? Is your project a java project? Do you have the JDK? — Cubic, Jan 06 '13 at 11:53

There must be an installed (and selected) JDK in Eclipse:
```
Window > Preferences > Java > Installed JREs   
```
The project must be configured to use that JDK:
```
Project > Properties > Java Build Path > Libraries
```
there should be an entry like "JRE System Library [JDK7]" in the list. If not press:
```
Add Library... > JRE System Library
```
The project should have been created as a "Java Project":
```
Project > Properties > Builders
```
should include "Java Builder"

The accepted answer did not work for me.

This is how I solved it:

Right-Click on your project, select Properties

Go to Java Build Path

Click Libraries, then Add Library ...

Select JRE System Library

Click on Execution environment and select JavaSE-1.7 or JavaSE-1.8

Click Finish, then Apply and Close.

This should have been an accepted solution. It worked for me too! – code_conundrum Oct 22 '22 at 08:13

Try to Update the execution environment under system library to JavaSE-1.7 or JavaSE-1.8 in eclipse. To update the step below can be followed:

> Right-click on the project
> Select properties
> Java build path
> Library > Add Library > Add JRE SYSTEM Library
> Execution Environment
> Select JavaSE-1.7 or JavaSE-1.8
> Finish

In the beginning when you start to create a new java project just don't click "finish" or "next" directly. But go to the JavaSE version text input at the middle of the form and choose JavaSE 1.6 or 1.7 or 1.8, then click next -> finish. Then it with parse and work.
