java.io.FileOutputStream class is used to write string into a file in java. If the file does not exists at the path provided, FileOutputStream class first creates the new file.
With FileOutputStream, no need to check if File exists and no need to create the file.
The constructor takes the java.io.File object and creates the new file.
Its very important to call the close() method on the FileOutputStream otherwise contents will not be written to the file created.
The difference between FileWriter to write into File and FileOutputStream is FileWriter write() method takes String content whereas FileOutputStream write() method takes bytes to write the content to file.
To convert String to bytes, use getBytes() method of String class
This implementation will over write the content in the file. If you want to append the content to end of existing file click FileOutputStream Append String to End of Existing File in Java
