java静态变量通过类名赋值

public class MyClass {
    public static int staticVariable = 10;

    public static void main(String[] args) {
        System.out.println("staticVariable: " + MyClass.staticVariable); // 输出 10

        MyClass.staticVariable = 20; // 修改静态变量的值

        System.out.println("staticVariable: " + MyClass.staticVariable); // 输出 20
    }
}
