I have four binary string stored in an array:     I want to randomly change one bit of the String in each array. From 0 to 1 or 1 to 0. Is there an easy way to change one bit in a string? Thank you for any help.
Assuming that I am reading your question correctly, you are stating that you have an array containg four strings:
To answer your question: You can't. Strings are immutable objects; that means, once assigned a value, they cannot change. Do not fear, however! Java is not a language that would leave you hanging like that. Use the StringBuffer class -- it is mutable.
(If you can follow how that bit of code works, then you're doing well....)

Thanks for the help that worked perfectly. Do you know if you can create an array of stringbuffers?
