Java's built-in exceptions are predefined exception classes in Java that the Java runtime system uses to handle common abnormal conditions. Here are some of them:

1. `ArithmeticException`: This exception is thrown when an exceptional arithmetic condition has occurred. For example, dividing by zero.

2. `ArrayIndexOutOfBoundsException`: This exception is thrown to indicate that an array has been accessed with an illegal index. The index is either negative or greater than or equal to the size of the array.

3. `ClassNotFoundException`: This exception is thrown when an application tries to load in a class through its string name using certain methods within class `ClassLoader` and that class cannot be found.

4. `FileNotFoundException`: This exception is thrown during a failed or interrupted I/O operations if the file does not exist.

5. `IOException`: This is the general class of exceptions produced by failed or interrupted I/O operations.

6. `InterruptedException`: Thrown when a thread is waiting, sleeping, or otherwise occupied, and the thread is interrupted, either before or during the activity.

7. `NoSuchFieldException`: Thrown when a class does not contain the field (or variable) specified.

8. `NoSuchMethodException`: Thrown when a particular method cannot be found.

9. `NullPointerException`: Thrown when an application attempts to use null in a case where an object is required.

10. `NumberFormatException`: Thrown to indicate that the application has attempted to convert a string to one of the numeric types, but that the string does not have the appropriate format.

11. `RuntimeException`: This is the superclass of those exceptions that can be thrown during the normal operation of the Java Virtual Machine.

12. `StringIndexOutOfBoundsException`: Thrown by `String` methods to indicate that an index is either negative or greater than the size of the string.

Each of these exceptions serves a specific purpose and helps in handling different types of errors that may occur during the execution of a Java program.
