Both string and string buffer are different ,in the case of
the String it can ready only and immutable where as the
String Buffer is the modifier and mutable.
EX:
String s1="abc";
S.o.p(s1);---------->o/p is abc
StringBuffer sb=new StringBuffer("abc");
s.o.p(sb);---------->o/p is abc
here we can modify the String buffer values if we want i.e
sb.append("z");
s.o.p(sb);----------->0/p is abcz

"this is the basic difference between the String and String
Buffer."
