java - How to turn Binary String into text? -

i working on personal project. want create encryption program lets encrypt, , decrypt string using key. finished need final part. want convert binary string text. let's binary outcome(which want convert normal text) is:

01001000011000010110100001100001 

this converted text "haha".

note: working bigintegers since every number using big normal integer.

edit: found answer using this code:

    stringbuffer output = new stringbuffer(); (int = 0;i < input.length();i += 8) {   output.append((char) integer.parseint(input.substring(i, + 8), 2)); }        system.out.println(output); 

this code in 1 line:

string str = "01001000011000010110100001100001";  string decoded = arrays.stream(str.split("(?<=\\g.{8})"))     .map(s -> integer.parseint(s, 2))     .map(i -> "" + character.valueof((char)i.intvalue()))     .collect(collectors.joining("")); // "haha" 

it can made prettier, didn't have ide handy (just thumbed in on phone).

you'll note biginteger isn't needed, , code handles input of arbitrarily large length.
