File.open("foo.txt", "w"){|f| f.write("foo")} We can write it
File.write("foo.txt", "foo") Is there simpler way to write this one?
File.open("foo.txt", "a"){|f| f.write("foo")}

Likewise, the text to be added is stored in the variable text . Then, inside a try-catch block we use Files ' write() method to append text to the existing file. The write() method takes the path of the given file, the text to the written, and how the file should be open for writing.
