You might not have Java SDK installed in your machine, or your Java SDK is not properly installed. Thus, please try to reinstall the Java SDK and run the SQL Developer again.
您的机器上可能没有安装 Java SDK，或者您的 Java SDK 没有正确安装。因此，请尝试重新安装 Java SDK 并再次运行 SQL Developer。

The class it is looking for (i.e. java.util.logging.FileHandler) is part of the JRE (or JDK).
它正在寻找的类（即java.util.logging.FileHandler）是 JRE（或 JDK）的一部分。
So, do you have any JRE or JDK (and which version) installed on your machine? Did you also set the JAVA_HOME environment variable?
那么，您的机器上是否安装了任何 JRE 或 JDK（以及哪个版本）？您是否还设置了 JAVA_HOME 环境变量？
