Does a finally block always get executed in Java?

Question

Considering this code, can I be absolutely sure that the finally block always executes, no matter what something() is?

try         


        

Answer 1

No, not always one exception case is// System.exit(0); before the finally block prevents finally to be executed.

  class A {
    public static void main(String args[]){
        DataInputStream cin = new DataInputStream(System.in);
        try{
            int i=Integer.parseInt(cin.readLine());
        }catch(ArithmeticException e){
        }catch(Exception e){
           System.exit(0);//Program terminates before executing finally block
        }finally{
            System.out.println("Won't be executed");
            System.out.println("No error");
        }
    }
}
