Can you list the main classes that extend Throwable in Java?

In Java, the class Throwable is the superclass for all errors and exceptions. The main classes extending Throwable are:

• Error — errors that are usually not handled by the application (e.g., OutOfMemoryError, StackOverflowError).
• Exception — exceptions that can and should be handled.

Subclasses of Exception are divided into:

• Checked exceptions, for example:

  • IOException
  • SQLException
  • ClassNotFoundException

• Unchecked exceptions, which inherit from RuntimeException, for example:

  • NullPointerException
  • IllegalArgumentException
  • IndexOutOfBoundsException

Thus, the main classes extending Throwable are:

Throwable
├── Error
└── Exception
    ├── RuntimeException
    └── (checked exceptions)

In Android, as in standard Java, the same exception classes are used.
