For example String str = "This " + is +" a dynamic" + string; Uses a single StringBuilder object behind the scene and is there for is as effective as using it explicitly, e.g. StringBuilder sb = new StringBuilder(); sb.append("This ").append(is) .append(" a dynamic").append(string); String str = sb.toString(); Don't be surprised that because StringBuffer implementation is slower than that of StringBuilder, the expression which uses + is faster than using a StringBuffer explicitly (quite common in pre 1.5 java code). It's easy to write a tiny test class to prove it. I think this artice misses the point about using multiple + in a single expression.
For example
String str = “This ” + is +” a dynamic” + string;
Uses a single StringBuilder object behind the scene and is there for is as effective as using it explicitly, e.g.

StringBuilder sb = new StringBuilder();
sb.append(“This “).append(is)
.append(” a dynamic”).append(string);
String str = sb.toString();

Don’t be surprised that because StringBuffer implementation is slower than that of StringBuilder, the expression which uses + is faster than using a StringBuffer explicitly (quite common in pre 1.5 java code).

It’s easy to write a tiny test class to prove it.
