What is the best way to emulate try-with-resources in Java 6?

Question

It turns out that almost nobody closes resources in Java correctly. Programmers either do not use try-finally block at all, or just put resource.close()

Answer 1

Though anonymous class is quite verbose, it's still acceptable in java land

    new TryWithResource(){
        protected InputStream init() throws Exception {
            return new FileInputStream("abc.txt");
        }
        protected void use(InputStream input) throws Exception{
            input.read();
        }
    };

----

abstract class TryWithResource
{
    abstract protected R init() throws Exception;
    abstract protected void use(R resource) throws Exception;

    // caution: invoking virtual methods in constructor!
    TryWithResource() throws Exception
    {
        // ... code before
        R r = init();
        use(r);
        // ... code after
    }
}
