The highest class in the hierarchy among the ones you mentioned is java.lang.Object. In Java, all classes, including the ones you mentioned, inherit either directly or indirectly from the java.lang.Object class. Here is the hierarchy:

1. java.lang.Object: This is the root of the class hierarchy. Every class has Object as a superclass.

2. java.lang.Throwable: The Throwable class is a subclass of Object. It is the superclass of all errors and exceptions in the Java language.

3. java.lang.Exception: The Exception class extends Throwable. It's used for exceptional conditions that a user's program should catch.

4. java.lang.Error: The Error class also extends Throwable. It's used for serious problems that a reasonable application should not try to catch, as they are abnormal conditions.

So, the hierarchy is as follows: Object Throwable (Exception, Error).
