You can do crazy things in every language. However, in a language like Java, the crazy things are more conceptual (factory for factory of factories) and not basic things like what does == mean or problems with weak typing and implicit conversions. A lot of the issues with PHP can be avoided in modern PHP using things like strict_types=1, but most of the time, we don't get to work with projects using best practices. And I'd rather work with a bad Java project than any bad PHP project (which I have had the misfortune of maintaining).

Funny that you picked == as an example when == is very counter intuitive in Java and is one of the common pitfalls for beginners:

    String a = new String();
    String b = new String();
    a = "test";
    b = a + "";
    
    if (a == "test")
    {
        // true
    }

    if (b == "test")
    {
        // false
    }

    if (a == b)
    {
        // false
    }
