Yes, an exception can be rethrown.
Yes, in Java, an exception can be rethrown. When a catch block catches an exception, it has the option to handle the exception locally or to rethrow it. If the catch block decides to rethrow the exception, it means that it doesn’t handle the exception itself, but instead, it passes the exception to the calling method or a higher level in the call stack.
Here’s an example:
public class RethrowExample {
public static void main(String[] args) {
try {
someMethod();
} catch (Exception e) {
System.out.println("Exception caught in main: " + e.getMessage());
}
}
public static void someMethod() throws Exception {
try {
// Some code that may throw an exception
throw new Exception("This is an example exception");
} catch (Exception e) {
System.out.println("Exception caught in someMethod: " + e.getMessage());
// Rethrow the exception
throw e;
}
}
}
In this example, someMethod catches an exception, performs some local handling, and then rethrows the exception. The calling method, main in this case, can catch the rethrown exception or let it propagate further up the call stack.
