java - How to check another condition before set AtomicBoolean? -

-

i have atomicboolean , want set it, if condition true:

for example have bankaccount active , saldo field. in method setinctive, have check if saldo field 0 , set active field false.

this solution, i'm not sure if works!

private final atomicboolean active = new atomicboolean(true); private final atomicreference<double> saldo = new atomicreference<>(0.0);  @override public boolean setinctive() {     //first: check if saldo 0.0     //second: set active false      saldo.getandupdate(adouble ->  {         if(adouble == 0)             active.set(false);          return adouble;     });      //return negated value of active field     return !active.get(); }

what correct solution atomics , possible without using locks?

one possible way , check condition , set boolean, use atomicmarkablereference. im example of type double:

private final atomicmarkablereference<double> saldo = new atomicmarkablereference<>(0.0, true);  @override public boolean setinctive() {     return saldo.attemptmark(0.0, false); }

the saldo field represents not current saldo, status of bank account.

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
