Writing to text file java

This method can take four parameters. These are file path, character sequence, charset, and options. The first two parameters are mandatory for this method to write into a file.

It writes the characters as the content of the file. It returns the file path and can throw four types of exceptions. It is better to use when the content of the file is short.

Example: It shows the use of the writeString method that is under the Files class to write data into a file. Another class, Path, is used to assign the filename with a path where the content will be written. Files class has another method named readString to read the content of any existing file that is used in the code to check the content is properly written in the file.

IOException; import java. Files; import java. Method 2: Using FileWriter Class If the content of the file is short, then using the FileWriter class to write in the file is another better option.

It also writes the stream of characters as the content of the file like writeString method. The constructor of this class defines the default character encoding and the default buffer size in bytes.

Without the path, the file will be written the current "working" directory, which is typically the directory the program was executed in Try adding System.

Since the append parameter is for FileWriter not BufferedWriter. I would like to add a bit more to MadProgrammer's Answer. In case of multiple line writing, when executing the command writer.

The following program writes the name of four oceans to the text file. During program execution, various things can happen — For example, suppose you create a PrintWriter object and pass the name of a file to its constructor The PrintWriter object attempts to create the file, but unexpectedly the disk is full and the file cannot be created.

If such things happen, we say that an exception has occurred. If an exception occurs in a method, then the method should either handle the exception or throw it for the calling environment to handle. In next chapter you will learn all about exceptions, but for now, we will simply allow our methods to throw any exceptions that might occur.

For example our main method should look like this :. When above program is compiled and run output is stored in text file oceans. The following figure shows the contents of the file displayed in Notepad. Remember that if a file that you are opening with the PrintWriter object with the name already exists in the directory it will be deleted and a new empty file with the same name is created.
