这是因为 Eclipse 的开发环境使用的是 JRE，我们需要把这里换成 JDK。

到 Windows 下面选择 preferences

970×764 279 KB

然后选择 【Installed JREs】

713×699 112 KB

选择【Add】新增

713×699 112 KB

选择【Standard VM】

输入选择 JRE 的目录

注意目录在这里需要选择为 JDK

525×540 116 KB

可以看到我们这里有 JDK 和 JRE ，我们可以只保留一个。

713×699 122 KB

单击 【OK】完成 JRE 的配置。

重新编译，我们会发现编译已经顺利通过了。
