i learning c++, beginner question. the iostream cin has error state error flag goodbit, eofbit, failbit, badbit can see how change putting them in watch? if have write? if not how can see how error state flags change? to display flags of cin in watch window while debugging: enter in watch window: std::cin.flags() or std::cin.good() etc. but: won't work right away. the default project configuration links c(++) runtime library dynamically (i.e. using dll). there seems issue debugger/watch have specify context of function if it's defined in dll, see this question . a quick workaround set project statically link c(++) runtime library; in vs2010 it's under project configuration -> c/c++ -> code generation -> runtime library -> set "multi-threaded debug" (instead of "multi-threaded debug dll").

i have object of custom class. need convert string can write file. there way out ? thanks help. you can't convert custom class string automatically. system has no way of knowing how want string formatted, want in , such. you have manually implement method in custom class returns text interpretation of object. override method called tostring() . method gets called automatically if provide instance of class methods. let's if system.out.println(instance) , instance 's tostring() method automatically invoked. i don't know custom class is. let's it's person class member variables string name , int age . tostring() method defined in class this: @override public string tostring() { return "name: " + name + ", age: " + age; } this provide output "name: name, age: 30".

i wondering advantages , disadvantages use html tag opposed achieving same scrolling text effect using javascript? is use of <marquee> html tag encouraged? you ask is use of <marquee> html tag encouraged? the w3.org answers : no, really. don't use it. you have no guarantee of marquee element support across future browsers , when it's present, of options might absent in today's browsers (for example tested mdn's examples in chrome , got different bouncing effect in firefox). most users prefer not see javascript based solution either, if need (like, boss asks it), search of "javascript marquee" gives many solutions, example very simple, smooth, javascript marquee javascript based solutions have advantages of being configurable , of not being based on non standard element ( "html5 classifies non-conforming feature.") .

can override tostring method of functional interface? or rephrase. there elegant way change anonymous inner class implements functional interface , overrides tostring method lambdas? can override tostring when create lamba expression in jdk8. interface iface { void do(); } main() { iface iface = () -> /*do something*/ system.out.println(iface); // see useful in output } can override tostring iface? no, lambda expressions used express 1 method interfaces if functions. it's element of functional languages implemented in java (an oop language). to override tostring, must implement interface in class.

my doubt is, have employee class contains 2 variable id , name follows: public class empbean { int id=10;; string name="uday"; } i have added object hashmap follows: hashmap<empbean, empbean> hashmap= new hashmap<empbean, empbean>(); hashmap.put(empbean, empbean); then: system.out.println(hashmap.get(empbean).id); output:10; when call get() method of hashmap ,it calculates hashcode , apply hashing on , finds bucket , returns value. so far fine. if want change hash code of object before calling get() method. how can ? tried empbean.id=2000; there no change in hashcode. if change value in object witch in hashmap must first remove item hashmap edit value , after insert hashmap again.

i'm going start developing java web app believe deploying cloudbees, concerned jre/sandbox restrictions may apply. for instance, google app engine, you're not allowed execute methods packaged inside java.io.file or java.net . you're not allowed start threads without using custom threadfactory . you're not allowed use jndi, jmx or make calls remote rdbmses hosted on 3rd party machines. you're not allowed use reflection. gae, there's a lot you're not allowed do. do these same restrictions hold true cloudbees? i'm guessing no , read entire developer docs , didn't run across of sort. however , happens if app tries write local file system when deployed servers? must have certain restrictions can run on machines, if no other reason security! so ask: these restrictions, or can find them listed in docs? in advance! last checked (a) there no sandbox; (b) can write local filesystem, files write there may discarded if application repr...
