what is difference in string and string buffer?

1.string is immutable where is string builder is mutable
2.In stringBuilder, automatically increase and decrease size of string object whenever add elements and delete elements .Where in string , it is fixed size .
3.StringBuilder can performe a insert(),Delete(),Reverse(),Sort() operations etc and we can create multiple instances .Where as String , It can't perfome .
4.StringBuilder takes enough memory for variable .Where as String can't perfome
