What is difference between String and StringBuffer in Java?
String is an immutable type (you can't change its contents once set). To "change" a string, like appending another string value to it, Java will actually create a new string object.
StringBuffer is a mutable string type (you *can* change its contents). You can modify the character data directly in a StringBuffer, or append strings to it without creating a third string, etc.
You should have no trouble at all finding sample code online for StringBuffer.AppendString().
What is difference between String and StringBuffer in Java?
i dont program in java much, but i do in c++ and they are very similar. i should be a string is the general term, and string buffer is specifying the size of the string, so the string will only hold a certian number of characters. for example in c++, you can define a string as
char string[] = "bla bla bla";
to add characters, but if u wanted to specify the buffer to be filled at a later time, u can say
char string[40];
with 40 characters including the hidden return character at the end and then later fill the string with stuff, not exceeding the limit of 40.
