Question

I have to use a method whose signature is like this

aMethod(FileInputStream);

I call that method like this

FileInputStream inputStream = new FileInputStream(someTextFile);
aMethod(inputStream);

I want to remove/edit some char which is being read from someTextFile before it being passed into aMethod(inputStream);

I cannot change aMethod’s signature or overload it. And, it just take a InputStream.
If method taking a string as param, then I wouldn’t be asking this question.

I am InputStream noob. Please advise.

Answer 1

you can convert a string into input stream

String str = "Converted stuff from reading the other inputfile and modifying it";
InputStream is = new ByteArrayInputStream(str.getBytes());
