Java - Built-in Exceptions

Advertisements

Java defines several exception classes inside the standard package java.lang.

The most general of these exceptions are subclasses of the standard type RuntimeException. Since java.lang is implicitly imported into all Java programs, most exceptions derived from RuntimeException are automatically available.

Java defines several other types of exceptions that relate to its various class libraries. Following is the list of Java Unchecked RuntimeException.

Sr.No. Exception & Description 1 ArithmeticException Arithmetic error, such as divide-by-zero. 2 ArrayIndexOutOfBoundsException Array index is out-of-bounds. 3 ArrayStoreException Assignment to an array element of an incompatible type. 4 ClassCastException Invalid cast. 5 IllegalArgumentException Illegal argument used to invoke a method. 6 IllegalMonitorStateException Illegal monitor operation, such as waiting on an unlocked thread. 7 IllegalStateException Environment or application is in incorrect state. 8 IllegalThreadStateException Requested operation not compatible with the current thread state. 9 IndexOutOfBoundsException Some type of index is out-of-bounds. 10 NegativeArraySizeException Array created with a negative size. 11 NullPointerException Invalid use of a null reference. 12 NumberFormatException Invalid conversion of a string to a numeric format. 13 SecurityException Attempt to violate security. 14 StringIndexOutOfBounds Attempt to index outside the bounds of a string. 15 UnsupportedOperationException An unsupported operation was encountered.
