Don't know why but when you compare two string it only accepts result with this construction:

if (text.equals(new String(textInFile))) { ... }
This one doesn't work:

if (text.equals(Arrays.toString(textInFile))) { ... }

I didn't even compare them in String form. What I used:

if(Arrays.equals(readBytes, text.getBytes())
I was able to pass using this comparison.

Writing to existing file: "If the file is too short", means that number will be bigger than your file length. Using RandomAcessFile - helpful example:

test.txt: Hi, good luck
String[] args = {"C:\test.txt",4,"good"}
Output:

Hi, good lucktrue
