Create a program RandomFile.java that generates files with random numbers/characters.

You arerequired to write the following three methods in the classRandomFile:

​publicstatic void randomBinaryFile(StringfileName,int length)

​publicstatic void randomNumberFile(StringfileName,intlength)

​publicstatic void randomCharFile(StringfileName,int length)

The parameter “fileName”specifies the file name, and “length” specifies the length of thesequence in the file.

● randomBinaryFile will generatea file containing a sequence of 0 or 1 of the specifiedlength;

● randomNumberFile will generatea file containing a sequence of digits 0, 1, 2, …, 9 of thespecified length;

● randomCharFile will generatea file containing a sequence of characters A, B, C, …, Z of thespecified length;

Also write a main()method to test your code. In the main()method, you may ask the user to type in a file name, a type ofrandomness (binary, digit or character), and the length of thefile.

The following code generates a random character between A andZ:

​​Randomr = new Random();​​

​​chara = (char) (r.nextInt(26)+ 'A');

Another way is as below:

Random r = new Random();​​

String alphabet = \"ABCDEFGHIJKLMNOPQRSTUVWXYZ\";

char a = alphabet.charAt(r.nextInt(26));
