Reading and Writing Files in Python.
BufferedWritter the simplest way to write the content to a file. It writes text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings.
We know that 100 MB are allocated for our StringBuilder; once it is converted into a String, another 100 MB are allocated for the String object and the last 200 MB are used getting the bytes from the original StringBuffer and writing the data to the file.
Writing binary data to file. To write binary data to file, we can use the Write method of the FileStream instance. As with the previous example, the following code writes the current date time string to the end of techcoil.txt. However, it converts the current date time string as bytes before writing to techcoil.txt.
For writing in file, it is easy to write string or int to file using fprintf and putc, but you might have faced difficulty when writing contents of struct. fwrite and fread make task easier when you want to write and read blocks of data. fwrite: Following is the declaration of fwrite function.
WriteAllLines (String, String (), Encoding) Creates a new file, writes the specified string array to the file by using the specified encoding, and then closes the file.
Create a text file from the command line.

FileWriter: FileWriter is the simplest way to write a file in Java. It provides overloaded write method to write int, byte array, and String to the File. You can also write part of the String or byte array using FileWriter. FileWriter writes directly into Files and should be used only when the number of writes is less.
