数组定义与类的初始化

---

SuperClass类：

public class SuperClass {
    public static String staticVariable = "staticVariable";
    public static final String STATIC_CONSTANT = "STATIC_CONSTANT";

    static {
        System.out.println("SuperClass is loading.");
    }
}

现有一段代码，创建了SuperClass数组：

public class MainClass {
    static {
        System.out.println("MainClass is loading.");
    }

    public static void main(String[] args) {
        SuperClass[] superClasses = new SuperClass[3];
    }
}

上述代码执行后，控制台输出：

MainClass is loading.

可见，通过数组定义来引用类，并不会触发类的初始化。
