How to write a newline into a file in java

This is because when using multiple platforms, and operating systems, using platform-independent line breaks is the most risk-free option because it is cross-compatible. It is a platform-independent line break which means that it will work just fine irrespective of any operating system.

You can also use System. See the code below demonstrating the System. Although line separator provides the platform independence as well as gets the job done, it is still a separator, not a newline character because it restricts the coder to concatenate the strings. Developers can either use it separately as mentioned in the first example or they have to use it with concatenation. There is also a way to add a Newline Characters to a string without concatenating multiple strings.

It is the same as including System. See this example:. It is a small and simple newline character but there is a small problem. Add a comment. Active Oldest Votes. Michael Michael Or, use a PrintWriter and writer. Polygnome Polygnome 7, 2 2 gold badges 31 31 silver badges 56 56 bronze badges. Ohhh, okay. I gotcha. So FileWriter isn't really the best for writing to a text file? PrintWriter is the good for writing to a file. At least if you want to write raw data.

But since you actually want to print text to a file, wrapping the FileWriter into a BufferedWriter or PrintWriter helps you dealing with that.

CodeAdmiral I think PrintWriter is the best choice for writing text to a file because, in addition to providing methods that write String objects, it provides methods that write other data types like int , float , and double. To output an int with FileWriter , you would have to convert it to a String: writer.

The method newLine is provided by BufferedWriter Could be ok as solution? One can use PrintWriter to wrap the FileWriter , as it has many additional useful methods.

To write text rather than raw bytes to a file you should consider using FileWriter.

You should also wrap it in a BufferedWriter which will then give you the newLine method. To write each word on a new line, use String. In order to write each word on a different line, you need to split up your input string and then write each word separately.

This creates a file, if it does not exist If files exists, it is uses the existing file and text is appended If you want everyline to be written to the next line add lineSepartor for newline into file.

You could print through a PrintStream. FileWriter is meant for writing streams of characters. For writing streams of raw bytes, consider using a FileOutputStream.
