Strings are immutable right ( mentioned in the text ) apart from theory i want to know the practical  application of that.......Like we often change the data of the string many times by using library functions like .toUpperCase or etc.....we use s=s.toLowerCase(); and we get the right output but why not it happens if we write directly s.toLowerCase instead of creating a seperate String object ?? i mean can anyone explain the diff and say how Strings are immutable...practical application is equally important right..so plz
