Answer 1

It's encrypted, read it as HEX/BIN

Answer 2

is it class file of Java program??

Answer 3

Basically go read up on Encryption/Decryption. Mainly RSA as that should be the one you are working on.
If you don't have the decryption key. Don't bother finding it unless you were provided with some other numbers. What numbers? Read up on Encryption/Decryption and you get what I mean.
Readup on padding schemes too, there are different types of it.

Answer 4

Can this be a programmer's text-handling lesson? You pasted binary data. The sequence 0xefbfbd (a diamond with ? in it) is the UTF-8 representation of the 'replacement character' 0xfffd. It's probably* mojibake (garbled text) and could've junked anywhere between your system and our devices (including SoloLearn):

- Note SoloLearn drops the ) on the link.

* Specials: "Since the replacement is the same for all errors this makes it impossible to recover the original character."

Answer 5

Use a hex editor and read the file. It should come out as a bunch of numbers. If you have the decryption key, use the decryption formula. After that, padding schemes to get the hidden message.
