Exception Handling

Exception Handling Information regarding Exception:-  Dictionary meaning of the exception is abnormal termination. An expected event that disturbs or terminates normal flow of execution called exception. If the application contains exception then the program terminated abnormally the rest of the  application is not executed. To overcome above limi tation in order to execute the rest of the application must handle the  exception. In java we are having two approaches to handle the exceptions. 1)  By using try-catch block. 2)  By using throws keyword. Exception Handling:- The main objective of exception handling is to get normal termination of the application in order to execute rest of the application code. Exception handling means just we are providing alternate code to continue the execution of remaining code and to get normal termination of the application. Every Exception is a predefined class present in different packages. java.lang.Arith

Wrapper classes Java is an Object oriented programming language so represent everything in the form of the object, but java supports 8 primitive data types these all are not part of object. To represent 8 primitive data types in the form of object form we required 8 java classes these classes are called wrapper classes. All wrapper classes present in the java.lang package and these all classes are immutable classes. Wrapper classes hierarchy Wrapper classes Constructor Integer i = new Integer(10); Integer i1 = new Integer("100"); Float f1= new Float(10.5); Float f1= new Float(10.5f); Float f1= new Float("10.5"); Character ch = new Character('a'); datatypes wrapper-class constructors byte Byte byte,String short Short short,String int Integer int,String long Long
