FileWriter is not writing in to a file

Question

        fileWriter.write(\"Hi this is sasi This t         


        

Answer 1

Closing was missing. Hence not the last buffered data was not written to disk.

Closing also happens with try-with-resources. Even when an exception would be thrown. Also a flush before close is not needed, as a close flushes all buffered data to file.

try (FileWriter fileWriter = new FileWriter("C:\\temp\\test.txt"))
{
    fileWriter.write("Hi this is sasi This test writing");
    fileWriter.append("test");
}
catch (IOException ioException)
{
    ioException.printStackTrace();
}
