The above figure describes the flow of program execution when an exception occurs while creating a new FileWriter. Each catch block will handle the independent exceptions. acknowledge that you have read and understood our, GATE CS Original Papers and Official Keys, ISRO CS Original Papers and Official Keys, ISRO CS Syllabus for Scientist/Engineer Exam, Difference between Abstract Class and Interface in Java, Access specifier of methods in interfaces, Access specifiers for classes or interfaces in Java, Dynamic Method Dispatch or Runtime Polymorphism in Java, Association, Composition and Aggregation in Java, Object Oriented Programming (OOPs) Concept in Java, Split() String method in Java with examples, finalize() method in Java and how to override it, Unreachable statement using final and non-final variable in Java, Flow control in try catch finally in Java, Static and non static blank final variables in Java, Difference between Final and Abstract in Java, Assigning values to static final variables in Java, Java.util.TreeMap.descendingMap() and descendingKeyset() in Java, Java.util.TreeMap.firstEntry() and firstKey() in Java, Java.util.TreeMap.containskey() and containsValue() in Java, Java.util.TreeMap.pollFirstEntry() and pollLastEntry() in Java.
La classe Exception est la superclasse de toutes les classes d'exceptions de l'API ; les exceptions correspondent en général à des événements inattendus, qui seront souvent traités de sorte qu'elle ne provoque pas l'arrêt du programme.
From Java SE 7 and later, we can now catch more than one type of exception with one catch block.
Check Out The Perfect Java Training Guide Here. The finally block executes the code enclosed in it regardless of whether the exception is thrown or not. In the above program, an ArithmeticException that is caught in the first catch block is raised.
It is because it includes important cleanup code such as: We have mentioned that finally always executes and that is usually the case.
This throws an ArithmeticException which is caught by the catch block. We can skip the finally block in exception handling code. The generic exception handler, object e of Exception class can handle all the exceptions but if we want to handle specific exceptions, then it is advisable to specify the generic exception handler as the last catch block.

If the try block does not raise any exception then the finally block will be executed after the try block.
In this tutorial, we will discuss various keywords used in Java for Exception Handling such as Try, Catch, Finally, Throw and Throws with examples: In our previous tutorials, we have seen the basics of exception handling in Java along with the various exceptions supported by Java Exception class.
public void division(int num1, int num2){
final(lowercase) is a reserved keyword in java. Download this example.
See your article appearing on the GeeksforGeeks main page and help other Geeks. }
When an exception occurs, it is caught by the catch block that immediately follows it. */
Exception. * This method is used to divide two integers. public static void main(String args[]){
This ensures that the finally block is executed even if an unexpected exception occurs.
Note: The finally block is a key tool for preventing resource leaks. * when exception occur but not handled.
System.out.println("Finally will always execute.
Please write to us at contribute@geeksforgeeks.org to report any issue with the above content. So in this case the program termination is Normal and not abnormal.
System.out.println("Remaining code after exception handling. //java.lang.ArithmeticException here.
We need such structures in certain situations when a piece of code contained in a try code may be such that some lines raise certain exceptions and another piece of code raises a completely different exception. In the last tutorial, we learned about exceptions. A try block inside another try block is called a nested try block. The general syntax of the try-catch block is shown below: The try block can have multiple lines of code that can raise multiple exceptions.
However, the question arises as to why we need a “throws” keyword when we have a more reliable try-catch block to declare and handle exceptions?
After that finally, execute since finally is meant to execute whether an exception occurs or not or whether corresponding catch block found/match or not.
