MessageFromBinaryCode.java

/*

You are taking part in an Escape Room challenge designed specifically for programmers. In your efforts to find a clue, you've found a binary code written on the wall behind a vase, and realized that it must be an encrypted message. After some thought, your first guess is that each consecutive 8 bits of the code stand for the character with the corresponding extended ASCII code.

Assuming that your hunch is correct, decode the message.

Example

For code = "010010000110010101101100011011000110111100100001", the output should be
messageFromBinaryCode(code) = "Hello!".

The first 8 characters of the code are 01001000, which is 72 in the binary numeral system. 72 stands for H in the ASCII-table, so the first letter is H.
Other letters can be obtained in the same manner.

String messageFromBinaryCode(String code) {

    for(String s1:s){
        char c=(char)Integer.parseInt(s1,2);
        res=res+c;
    }
    return res;
