sqlite exception :- Attempt to write readonly database

I have created a java application having sqlite db (using netbeans). I have also created a .exe file and the database is there in the folder containing the executable file. But when I run the .exe file read operation is working fine. When I try updating or writing on to db , am running into the following error. Java.sql.SQLException: Attempt to write a readonly database.

Erro Internal Exception: java.sql.SQLSyntaxErrorException: ORA-01775: looping chain of synonyms

Alterei minha query no repository colocando um DISTICT e retirando alguns campos que não eram mais utilizados e ao rodar o projeto recebi o erro:

Pelas minhas pesquisas, vi que isso é uma coisa que ocorre no database oracle mas não consegui identificar uma solução uma vez que nada foi alterado no banco, alguma idéia ?

Desde já obrigado.

Exception in thread “main” java.lang.NullPointerException – I worked with java files and Java Arraylist to store my

When I was Working on Java users Registration project it showed me this Exception in thread “main” java.lang.NullPointerException error. I worked with Java files and java ArrayList to store my signed up users. I think the error came with this line if (arrayList.get(i).getName().equals(user.getName())) Here is my code. Thank you….

public void deleteUser(User user) { database = new Database();

    ArrayList<User> arrayList = database.getArrayList();     for (int i = 0; i < arrayList.size(); i++) {          if (arrayList.get(i).getName().equals(user.getName())){             arrayList.remove(i);             System.out.println("Deleted");             break;         }     }      try (BufferedWriter writer = new BufferedWriter(new FileWriter(this.file))) {         for (int i = 0; i < arrayList.size(); i++) {             User u = arrayList.get(i);             writer.write(u.getName() + ":" + u.getPassword() + ":" + u.getEmail());             writer.newLine();         }     } catch (IOException ex) {         System.out.println(ex.getMessage());     } }

Doctest error al intentar capturar Exception Value error

Os reporto un error de testing. Intento capturar el error de introducir un valor negativo en una raíz cuadrada.

Mi código:

Exception Handling in Class

I have read a few sites on how to handle exceptions and I think I understand it better. Here is how I plan to handle it going forward. I used a lot of the guidelines here, https://isocpp.org/wiki/faq/exceptions.

Is this a sensible to handle it with c++14 as I’m using visual studio 2015. Would it be different with C++17?

#include <iostream> #include <exception> #include <string>  #define THROWFOORTE(what) throw FooRuntimeException(what, __FILE__, __func__, __LINE__) #define THROWFOORE(what) throw FooRangeError(what, __FILE__, __func__, __LINE__)  struct FooRuntimeException     : public std::runtime_error {     FooRuntimeException(const char* what,          const char* file, const char* func, int line)         : runtime_error(std::string(file) +":" +              std::string(func) + ":" + std::to_string(line)              + " " + std::string(what)) {} };  struct FooRangeError     : public std::range_error {     FooRangeError(const char* what,         const char* file, const char* func, int line)         : range_error(std::string(file) + ":" +             std::string(func) + ":" + std::to_string(line)             + " " + std::string(what)) {} };  class Foo { public:     Foo() = default;     ~Foo() {};      void throwRunTimeException()     {         THROWFOORTE("Runtime Error");     }     void throwRangeError()     {         THROWFOORE("Range Error");     } };  void HandleException() {     try { throw; }     catch (const FooRuntimeException &e)     {         std::cerr << e.what() << '\n'; // catches standard error message     }     catch (const FooRangeError&e)     {         std::cerr << e.what() << '\n';; // catches standard error message     }     return; }  int main() {     try     {         auto foo = Foo();         foo.throwRunTimeException();     }     catch (...) {         HandleException();     }        try     {         auto foo = Foo();         foo.throwRangeError();     }     catch (...) {         HandleException();     }      return 0; } 

Break iterations after an exception happens without data loss

I have this code that reads a file and after processing a few lines writes the output to a second file:

num_reads = 7 with open('data.txt') as read_file:     with open('new_data.txt', 'w') as write_file:          while (True):             lines = []             try:       # expect errors if the number of lines in the file are not a multiplication of num_reads                 for i in range(num_reads):                          lines.append(next(read_file))  # when the file finishes an exception occurs here                  #do sutff with the lines (exactly num_reads number of lines)                 processed = " ".join(list(map(lambda x: x.replace("\n", ''), lines)))                 write_file.write(processed + '\n')              except StopIteration:     # here we process the (possibly) insufficent last lines                 #do stuff with the lines (less that  num_reads)                 processed = " ".join(list(map(lambda x: x.replace("\n", ''), lines)))                 write_file.write(processed + '\n')                 break 

Assuming that I wish to do the same processing and writing procedure in both cases (when the number of elements is 7 and when the file finishes sooner). The above code violates DRY principle even if I define a new function and call it once in try block and once in except before break. Any other ordering that I could come up with was either causing an infinite loop or losing the final lines. I appreciate any comments on handling this issue, as it is not limited to this case and I had faced it in other cases as well.
