Why static block is not executed

Question

As per java doc, static block is executed when the class is initialized.

Could anyone please tell me why static block is not executed when I run below code?

class A {
    static {
        System.out.println("Static Block");
    }
}

public class Main {

    public static void example1() {
        Class<?> class1 = A.class;
        System.out.println(class1);
    }


    public static void example2() {
        try {
            Class<?> class1 = Class.forName("ClassLoading_Interview_Example.ex1.A");
            System.out.println(class1);
        }catch(Exception e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        example1();
    }
}

Answer 1

类的静态初始化通常在第一次发生以下事件之前立即发生：

• 创建该类的实例，
• 调用类的静态方法，
• 分配了类的静态字段，
• 使用非常量静态字段，或 [...]

您目前没有执行上述任何操作。所以，通过替换

Class<?> class1 = A.class;
System.out.println(class1);

以此为例

A object = new A();

会给你你的结果。
