what is stringbuilder?

StringBuilder is more efficient in the cases, where a lot of manipulation is done to the text. Strings are immutable, so each time it's being operated on, a new instance is created. (More...)

String is immutable & StringBuilder is mutable.
Means we can add, remove or append the words in stringbuilder but not in string. And stringbuilder have larger range of storing than string. (More...)

-- System.String is immutable; System.StringBuilder can have mutable string where a variety of operations can be performed. (More...)

Objects of type stringBuilder are mutable, whereas objects of string are immutable (More...)

When we use string object ot concatenate two strings , the first string is concatenate to the other string by creating a new copy in the memory as string object , and the old string is deleted , this process is very long so we say strings are immutable.SO we use string builder object where append method is used.
Stringbuilder is faster than string operation as copy is done at the same loication (More...)

String Class
Once the string object is created, its length and content cannot be modified.
Slower
StringBuilder
Even after object is created, it can be able to modify length and content.
Faster (More...)

String and StringBuilder classes are used to store string values but the difference in them is that String is immutable (read only) by nature, because a value once assigned to a String object cannot be changed after its creation. When the value in the String object is modified, a new object is created, in memory, with a new value assigned to the String object. On the other hand, the StringBuilder class is mutable, as it occupies the same space even if you change the value. The StringBuilder class is more efficient where you have to perform a large amount of string manipulation. (More...)

StringBuilder is more efficient in cases where there is a large amount of string manipulation. Strings are immutable, so each time a string is changed, a new instance in memory is created. (More...)
