The use of the '+=' operator for appending strings causes the JVM to create and use an internal StringBuffer. If a non-trivial number of these concatenations are being used then the explicit use of a StringBuilder or threadsafe StringBuffer is recommended to avoid this.
Example:
public class Foo {
void bar() {
String a;
a = 'foo';
a += ' bar';
// better would be:
// StringBuilder a = new StringBuilder('foo');
// a.append(' bar');
}
}
