Does a finally block always get executed in Java?

Question

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

try         


        

Answer 1

Adding to @vibhash's answer as no other answer explains what happens in the case of a mutable object like the one below.

public static void main(String[] args) {
    System.out.println(test().toString());
}

public static StringBuffer test() {
    StringBuffer s = new StringBuffer();
    try {
        s.append("sb");
        return s;
    } finally {
        s.append("updated ");
    }
}

Will output
