这个错误信息通常出现在使用Java编译器编译代码时,编译器无法确定要使用的JDK版本。解决这个问题的方法是明确指定要使用的JDK版本。
你可以在命令行中使用"-source"和"-target"选项来指定要使用的JDK版本,例如:
```
javac -source 1.8 -target 1.8 HelloWorld.java
```
上面的命令将使用JDK 1.8版本来编译HelloWorld.java文件。
另外,如果你使用的是集成开发环境(IDE),那么你需要确保在IDE的设置中指定了要使用的JDK版本。

Project JDK is not defined
"Project JDK is not defined"的错误意味着项目中未定义了JDK(Java Development Kit)。JDK是用于开发Java应用程序的软件开发工具包。这个错误通常出现在你创建一个新的模块并编辑.class文件时。
为了解决这个问题,你需要设置项目的JDK。你可以通过以下步骤完成设置:
1. 打开你的项目,并在菜单栏中选择"File",然后选择"Project Structure"。
2. 在弹出的窗口中,找到"Module SDK"选项,点击修改。
3. 选择正确的JDK版本并点击"OK"来完成设置。
完成以上步骤后,你的项目将能够找到正确的JDK,并且错误信息"Project JDK is not defined"将不再出现。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

project JDK is not defined
It seems like you are facing an issue with your Java Development Kit (JDK) not being defined.
To resolve this issue, you may need to check if the JDK is installed on your system and if the path to the JDK is set correctly in your system environment variables.
Here are the steps to check if JDK is installed:
1. Open a command prompt or terminal window.
2. Type `java -version` and press Enter.
3. If JDK is installed, you will see the version information displayed. If not, you will need to download and install the JDK.
Once you have confirmed that JDK is installed, you can check if the path to the JDK is set correctly:
1. Right-click on My Computer or This PC and select Properties.
2. Click on Advanced system settings.
3. Click on the Environment Variables button.
4. Under System Variables, scroll down to find the Path variable and click Edit.
5. Check if the path to the JDK is included in the list of paths. If not, add it by clicking New and entering the path to the JDK.
6. Click OK to save the changes.
After these steps, try running your Java project again. If you still face issues, please provide more details about the error message you are receiving.
