面试题：私有构造方法类外部能访问吗，用什么方…

package com.swift.fanshe;

import java.util.List;

public class Fanshe {
    
    String name="swift";
    private Fanshe(List list) {
        System.out.println("list");
    }
}

package com.swift.fanshe;

import java.lang.reflect.Constructor;
import java.lang.reflect.InvocationTargetException;
import java.util.ArrayList;
import java.util.List;

import org.junit.Test;

public class TestFanshe {
    
    @Test
    public void test() throws ClassNotFoundException, NoSuchMethodException, SecurityException, InstantiationException, IllegalAccessException, IllegalArgumentException, InvocationTargetException {
        
        Class clazz=Class.forName("com.swift.fanshe.Fanshe");
        Constructor c=clazz.getDeclaredConstructor(List.class);
        c.setAccessible(true);//暴力打开私有构造
        Fanshe fanshe=(Fanshe) c.newInstance(new ArrayList());
        System.out.println(fanshe.name);
        
    }
}
