Does a finally block always get executed in Java?

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

try {  
    something();  
    return success;  
}  
catch (Exception e) {   
    return failure;  
}  
finally {  
    System.out.println("I don't know if this will get printed out");
}

Important to know.

Good to know, and makes sense as well. It seems that actually returning the value of return is what comes after finally. Calculating the return value (printX() here) still comes before it.

Nope. The code above should replace System.out.println("finally trumps return... sort of"); with System.out.print("finally trumps return in try"); return 42;

This answer is completely self-evident IMO because return doesn't return some magic continuation that only gets evaluated if the caller prints it or whatever. printX() gets called before the return happens, regardless of any try/catch, or anything else.
