Java – How to we prepend strings with StringBuilder

c++javastringbuilder

I know we can append strings using StringBuilder. Is there a way we can prepend strings (i.e. add strings in front of a string) using StringBuilder so we can keep the performance benefits that StringBuilder offers?

Best Solution

Using the insert method with the position parameter set to 0 would be the same as prepending (i.e. inserting at the beginning).

C# example : varStringBuilder.Insert(0, "someThing");

Java example : varStringBuilder.insert(0, "someThing");

It works both for C# and Java
