int intVal = Convert.toInt(someObject, 0); // Default 0 on error/null String[] strArray = Convert.toStrArray("[a, b, c]"); Creating lists in old Java was verbose. Hutool 2.6 offered shortcuts that felt revolutionary at the time:
if(StrUtil.isBlank(userInput)) { ... } String upperFirst = StrUtil.upperFirst("hello"); // "Hello" String hide = StrUtil.hide("123456789", 2, 6); // "12****89" Tired of Integer.parseInt() throwing NPEs on null? The Convert class handled everything gracefully. hutool 2.6
Today, let’s rewind the clock and look at —a version that, while ancient by today’s standards (released years before modules and records), represented a sweet spot of simplicity and utility. What was Hutool 2.6? For the uninitiated, Hutool is a tiny, powerful Java utility library. Think of it as a "Swiss army knife" for Java, filling the gaps left by Apache Commons and Google Guava. Version 2.6 was a stable release from the project's early "pre-3.0" era. int intVal = Convert
In version 2.6, Hutool wasn't trying to be a massive framework. It was just a jar (roughly 100-150KB) that solved real, painful, repetitive problems. Let's be clear: You should not use Hutool 2.6 in a modern production environment. It lacks modules, uses old date/time APIs, and has zero support for java.time . The Convert class handled everything gracefully
