I wondered if I could reimplement this method without looking at the source. No problem: class SlightlyAtomicInteger { private final AtomicReference < Integer > reference = new AtomicReference <>( 0 ); public int incrementAndGet () { while ( true ) { Integer oldValue = reference . get (); Integer newValue = oldValue + 1 ; if ( reference . compareAndSet ( oldValue , newValue )) { return newValue ; } } } } IDE inspection told me: “Psst, you can change newValue declaration to int ”. I thought: “Why not? Oh, and I’ll change oldValue to int too”. As you may have guessed from the title, I shouldn’t have done that.
