there 2 types of iterators in java: fail-safe , fail-fast. what mean, , difference between them? what difference between them ... "fail safe" means: won't fail. strictly speaking, there no such thing in java fail-safe iterator. correct term "weakly consistent". javadoc says: "most concurrent collection implementations (including queues) differ usual java.util conventions in iterators , spliterators provide weakly consistent rather fast-fail traversal." typically, weak consistency means if collection modified concurrently iteration, guarantees of iteration sees weaker. (the details specified in each conncurrent collection classes javadocs.) "fail fast" means: may fail ... , failure condition checked aggressively failure condition (where possible 1 ) detected before damage can done. in java, fail-fast iterator fails throwing concurrentmodificationexception . the alternative "fail-fast" , "

here question: write program allows input integer represents month number (1 – 12) , program should display abbreviation corresponding month. example: if input 3, output should mar, march. hint: store month abbreviations in big string months = “janfebmaraprmayjunjulaugsepoctnovdec” here codes far: #include <iostream> using namespace std; int main() { int x; string months = "janfebmaraprmayjunjulaugsepoctnovdec"; cout << "enter integer between (1-12): " << endl; cin>>x; cout<<"\n"<<months.substr(x,3); return 0; } problem: cannot figure out how corresponding abbreviations. #include <iostream> using namespace std; int main() { int x; string months = "janfebmaraprmayjunjulaugsepoctnovdec"; cout << "enter integer between (1-12): " << endl; cin >> x; cout << months.substr((x-1)*3, 3); return 0; } se

i'm using rest:0.8 connect main grails project grails project serves report generator using line of code: map<string, string> adminconfigservice = [ weburl: "http://192.168.20.21:8080/oracle-report-service/generate", ... ] map params = [ ... name: "iñigo", ... ] withhttp(uri: adminconfigservice.weburl) { html = get(query: params) } and receiving rest client process data. running 2 projects in local machine works fine. although when deploy war file of report generator our tomcat server, converts letter "ñ" "├â┬æ" , name "iñigo" treated "i├â┬æigo" . since report generator project works fine when run on local machine, means need change conf files on tomcat server? setting file need change? it seems encoding issue. check config.groovy : grails.converters.encoding = "utf-8" check file's encoding of controllers , services use rest:0.8. check ur
