Java 到底是值传递还是引用传递？

后续补笔记，先写个demo

package com.example.demo.util;

/**

public class TestBoolean {
    public static void main(String[] args) throws Exception {
        boolean flag = true;
        test(flag);
        System.out.println(flag);
    }

    public static void test(boolean flag) {
        flag = false;
        System.out.println("test方法 " + flag);
    }
}
