String class is used to manipulate character strings that
cannot be changed.Simply stated,objects of the String are
read only and immutable.
StringBuffer class is used to represent characters that can
be modified.
Ex:Sting str=new String("core");
str +="Java";
StringBuffer str=new StringBuffer("core");
str.append("Java");

Answer / ashish ranjan
The main difference between String and StringBuffer is that String is Immutable, which means that we cannot modify the object which is created by the String.
As for Example.
String str = "abc";
now,
str = "abc" + "pqr";
the result is abcpqr. The previous value of str is not modified. It exists in the memory. Java Created new memory for str, which refers abcpqr.
now in case of StringBuffer
StringBuffer str = new StringBuffer("abc");
str.append("pqr");
it modifies in the same object.
