Object Oriented Programming

Write a Java program to check if a file specified by a pathname (take pathname as input from the user) exists or not. If it is a text file & contains any character except English alphabet & number then delete all those invalid characters & rewrite the converted texts to another file named output.txt. [Hint: Consider ASCII values of the characters to filter characters.]

But that is not for them to decide. All we have to decide is what to do with the time that is given us.
