Exception Handling In Java

Exception:  An Exception is an abnormal situation (or) unexpected situation in the normal flow of the program execution.  An exception is an abnormal condition that arises in a code sequence at run time.  Because of Exceptions the flow of program execution is getting disturbed so that program execution may continue (or) may not be continued. Types of exceptions: There are two types of exceptions: 1) Checked exceptions 2) Unchecked exceptions Checked exceptions: Checked exceptions are checked at compile-time. It means if a method is throwing a checked exception then it should handle the exception using try catch block or it should declare the exception using throws keyword, otherwise the program will give a compilation error. It is named as checked exception because these exceptions are checked at Compile time. Unchecked Exceptions: Runtime Exceptions are also known as Unchecked Exceptions as the compiler do not check whether the programmer has handled them or not but it’s the duty of the programmer to handle these exceptions and provide a safe exit. Here are the few most frequently seen unchecked exceptions – • NullPointerException • ArrayIndexOutOfBoundsException • ArithmeticException • IllegalArgumentException
