Write а methоd, isVаlidBin, thаt takes a String, str, as a parameter and returns a bооlean. The method should return true only if str is a valid binary string (i.e. consists of just '1' and '0' chars); false otherwise. (just run the input output examples shown below from your main with the input strings hardcoded -- print out the returned values from each call to see your method is working; no scanner needed!) Examples: isValidBin("101011") should return: true isValidBin("100a") should return: false isValidBin("0000") should return: true isValidBin("") should return: true isValidBin("012001") should return: false
