How to save a file with custom extension?

I am working on a project which creates a file with .bat extension.

In C++ it is possible by using

fstream myfile ("example.bat");
fstream<<"echo \"hello\" ";

But how can I do it in Java (JDK 8)?

I think this code does what you want. createFile will throw FileAlreadyExistsException if specified file already exists.

Path myBat = Paths.get("example.bat");
Files.createFile(myBat);
try( BufferedWriter reader = Files.newBufferedWriter(myBat) ) {
    reader.append("hello");
}

Edit:

I think try-with-resources is needed here.

I would suggest reading up on Java File IO. Whatever you want to call the file you're saving, you can. There aren't any custom extensions as opposed to normal extensions.
