Java.lang.Exceptions

The java.lang.Exceptions provides for different exceptions thrown under java lang package.

Exception Summary

S.N.	Exception & Description
1	ArithmeticException This is Thrown when an exceptional arithmetic condition has occurred.
2	ArrayIndexOutOfBoundsException This is Thrown to indicate that an array has been accessed with an illegal index.
3	ArrayStoreException This is Thrown to indicate that an attempt has been made to store the wrong type of object into an array of objects.
4	ClassCastException This is Thrown to indicate that the code has attempted to cast an object to a subclass of which it is not an instance.
5	ClassNotFoundException This is Thrown when an application tries to load in a class through its string name using: The forName method in class Class.
6	CloneNotSupportedException This is Thrown to indicate that the clone method in class Object has been called to clone an object, but that the object's class does not implement the Cloneable interface.
7	EnumConstantNotPresentException This is Thrown when an application tries to access an enum constant by name and the enum type contains no constant with the specified name.
8	Exception This is the class Exception and its subclasses are a form of Throwable that indicates conditions that a reasonable application might want to catch.
9	IllegalAccessException This is an IllegalAccessException is thrown when an application tries to reflectively create an instance (other than an array), set or get a field, or invoke a method, but the currently executing method does not have access to the definition of the specified class, field, method or constructor.
10	IllegalArgumentException This is Thrown to indicate that a method has been passed an illegal or inappropriate argument.
11	IllegalMonitorStateException This is Thrown to indicate that a thread has attempted to wait on an object's monitor or to notify other threads waiting on an object's monitor without owning the specified monitor.
12	IllegalStateException The Signals that a method has been invoked at an illegal or inappropriate time.
13	IllegalThreadStateException This is Thrown to indicate that a thread is not in an appropriate state for the requested operation.
14	IndexOutOfBoundsException This is Thrown to indicate that an index of some sort (such as to an array, to a string, or to a vector) is out of range.
15	InstantiationException This is Thrown when an application tries to create an instance of a class using the newInstance method in class Class, but the specified class object cannot be instantiated.
16	InterruptedException This is Thrown when a thread is waiting, sleeping, or otherwise occupied, and the thread is interrupted, either before or during the activity.
17	NegativeArraySizeException This is Thrown if an application tries to create an array with negative size.
18	NoSuchFieldException The Signals that the class doesn't have a field of a specified name.
19	NoSuchMethodException This is Thrown when a particular method cannot be found.
20	NullPointerException This is Thrown when an application attempts to use null in a case where an object is required.
21	NumberFormatException This is 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.
22	RuntimeException This is RuntimeException is the superclass of those exceptions that can be thrown during the normal operation of the Java Virtual Machine.
23	SecurityException This is Thrown by the security manager to indicate a security violation.
24	StringIndexOutOfBoundsException This is Thrown by String methods to indicate that an index is either negative or greater than the size of the string.
25	TypeNotPresentException This is Thrown when an application tries to access a type using a string representing the type's name, but no definition for the type with the specified name can be found.
26	UnsupportedOperationException This is Thrown to indicate that the requested operation is not supported.

Java - Built-in Exceptions

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.

Exception	Description
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.
ClassCastException	Invalid cast.
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.
IndexOutOfBoundsException	Some type of index is out-of-bounds.
NegativeArraySizeException	Array created with a negative size.
NullPointerException	Invalid use of a null reference.
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.
UnsupportedOperationException	An unsupported operation was encountered.

Following is the list of Java Checked Exceptions Defined in java.lang.

Exception	Description
ClassNotFoundException	Class not found.
CloneNotSupportedException	Attempt to clone an object that does not implement the Cloneable interface.
IllegalAccessException	Access to a class is denied.
InstantiationException	Attempt to create an object of an abstract class or interface.
InterruptedException	One thread has been interrupted by another thread.
NoSuchFieldException	A requested field does not exist.
NoSuchMethodException	A requested method does not exist.
