java.lang Errors and Exceptions Part - I

Some of the Errors and Exceptions of java.lang

AbstractMethodError: This is thrown when an application tries to call an abstract method.

ArithmeticException:  This is thrown when an exceptional arithmetic condition has occurred. For example, an integer "divide by zero" throws an instance of this class.

ArrayIndexOutOfBoundsException: This is thrown to indicate that an array has been accessed with an illegal index.

ArrayStoreException: This is thrown to indicate that an attempt has been made to store the wrong type of object into an array of objects.

AssertionError: This is thrown to indicate that an assertion has failed.

BootstrapMethodError: This is thrown to indicate that an invokedynamic instruction or a dynamic constant failed to resolve its bootstrap method and arguments.

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.

ClassCircularityError: This is thrown when the Java Virtual Machine detects a circularity in the superclass hierarchy of a class is loaded.

ClassFormatError: This is thrown when the Java Virtual Machine attempts to read a class file and determines that the file is malformed or otherwise cannot be interpreted as a class file.

ClassNotFoundException: Thrown when an application tries to load in a class through its string name using:

• The forName method in class Class.
• The findSystemClass method in class ClassLoader .
• The loadClass method in class ClassLoader.

but no definition for the class with the specified name could be found

CloneNotSupportedException: 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.

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.

ExceptionInInitializerError: It is thrown to indicate that an exception occurred during the evaluation of a static initializer or the initializer for a static variable.

IllegalAccessError: This is thrown if an application attempts to access or modify a field, or to call a method that it does not have access to.

IllegalAccessException: It 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.

IllegalArgumentException: This is thrown to indicate that a method has been passed an illegal or argument.

IllegalCallerException: This is thrown to indicate that a method has been called by an inappropriate caller.

IllegalMonitorStateException: This is thrown to indicate that a thread has attempted to wait on an object's monitor.

IllegalStateException: This signals that a method has been invoked at an illegal or inappropriate time.

IllegalThreadStateException: This is thrown to indicate that a thread is not in an appropriate state for the requested operation.

IncompatibleClassChangeError: This is thrown when an incompatible class change has occurred to some class definition.

IndexOutOfBoundsException: This is thrown to indicate that an index is out of range.

InstantiationError: This is thrown when an application tries to use the Java new construct to instantiate an abstract class or an interface.

ArrayIndexOutOfBoundsException code:

Approach:

Java:

public class IndexOut {
    public static void main(String[] args) {

        int arr[] = { 1, 2, 3, 4, 5 };

        System.out.println(arr[5]);
    }
}

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 5 out of bounds for length 5
