The answer to new String() - how max size of string we can pass using String constructor : should be Integer.MAX_VALUE. I infer this from the fact that string.length() returns an integer and the maximum value that an integer can have is Integer.MAX_VALUE which is approx 2^31 -1. In this String constructor we are just passing a String literal. Hence a String that has maximum length of Integer.MAX_LENGTH can be passed.
