how to create .CSV(MS-DoS) file in java

Answer 1

I assume that your issue is about the charset and not about the choice of CSV pattern. In Java, output stream uses the default charset, ie dixit Charset.defaultCharset() javadoc: the default charset is determined during virtual-machine startup and typically depends upon the locale and charset of the underlying operating system.

Unless you are working with a very old MSDOS os, it'd never be the case. The charset has to be specified with something like:

OutputStreamWriter os = new OutputStreamWriter(
            new FileOutputStream("FileFromNonJavaProgram.txt"), "Cp850" /* MS-DOS Latin-1 */);
