Change your thought process from “append a line break all but the last time” to “prepend a line break all but the first time”: boolean first = true; StringBuilder builder = new StringBuilder(); for (Map.Entry<MyClass.Key,String> entry : data.entrySet()) { if (first) { first = false; } else { builder.append(“\n”); // Or whatever break you want … Read more
