Determining which exception will be thrown when there is a throw in try, catch, and finally blocks

It is necessary to find out which specific exception will be thrown if the throw operator is used in each of the blocks — try, catch, and finally.

void runTask() {
    try {
        // ... throw new E1(...);
    } catch (E1 ex1) {
        // ... throw new E2(...);
    } finally {
        // ... throw new E3(...);
    }
}
