Maybe this helps...

Note the cleaner way to catch exceptions in the example below - you don't need the e instanceof IOException.

public static void foo() throws IOException {
    // some code here, when something goes wrong, you might do:
    throw new IOException("error message");
}

public static void main(String[] args) {
    try {
        foo();
    } catch (IOException e) {
        System.out.println(e.getMessage());
    }
}
