Replace StringBuffer / StringBuilder with String

Question

Why is NetBeans offering to replace StringBuffer/ StringBuilderwith String?

He shows me a warning when I write:

StringBuilder demo = new StringBuilder("Hello");

Answer 1

Instead of recording

StringBuilder demo = new StringBuilder("Hello");

it is simpler and you do not need to allocate a StringBuilder for it:

String demo = "Hello";

If you use a method that means it must be a StringBuilder, the warning should disappear.

eg.

StringBuilder demo = new StringBuilder("Hello");
demo.append(" World ");
demo.append(128);

Answer 2
