Question

How to insert a string enclosed with double quotes in the beginning of the StringBuilder and String?

Eg:

StringBuilder _sb = new StringBuilder("Sam");

I need to insert the string “Hello” to the beginning of “Sam” and O/p is “Hello Sam”.

String _s = "Jam";

I need to insert the string “Hello” to the beginning of “Jam” and O/p is “Hello Jam”.

How to achieve this?

Answer 1

The first case is done using the insert() method:

_sb.insert(0, "Hello ");

The latter case can be done using the overloaded + operator on Strings. This uses a StringBuilder behind the scenes:

String s2 = "Hello " + _s;
