Java defines several different classes inside the regular package java.lang.
The most common of these conditions are subclasses of the regular sort RuntimeException. Since java.lang is implicitly imported into all Java applications, many conditions derived from RuntimeException are automatically accessible.
Java identifies a few additional kinds of conditions that connect with its different type libraries. Following is the listing of Java Unchecked RuntimeException.
|ArithmeticException||Arithmetic error, such as divide-by-zero.|
|ArrayIndexOutOfBoundsException||Array index is out-of-bounds.|
|ArrayStoreException||Assignment to an array element of an incompatible type.|
|IllegalArgumentException||Illegal argument used to invoke a method.|
|IllegalMonitorStateException||Illegal monitor operation, such as waiting on an unlocked thread.|
|IllegalStateException||Environment or application is in incorrect state.|
|IllegalThreadStateException||Requested operation not compatible with current thread state.|

|NumberFormatException||Invalid conversion of a string to a numeric format.|
|SecurityException||Attempt to violate security.|
|StringIndexOutOfBounds||Attempt to index outside the bounds of a string.|
