If the runtime system exhaustively searches all the methods on the call stack without finding an appropriate exception handler, as shown in the next figure, the runtime system (and, consequently, the program) terminates. Searching the call stack for the exception handler. Using exceptions to ...
The import java.io.*; is used to import all the classes from the java.io package. The BufferedReader and InputStreamReader classes are then used to read input from the user, and the IOException is thrown in case of any errors. By using “import java.io.*;” we don’t have to speci...

By implementing AutoCloseable, resources can define their own close() method, which will be automatically invoked by the try-with-resources statement when the try block completes or if any exceptions are thrown, ensuring that resources are released properly without the need for explicit resource ...
