reflectObject(String package_class_name,String input) 该方法用于生成package_class_name所对应的类的实例对象，并初始化对象中的属性值。 举例： 入参：com.gec.Person, name=admin,sex=男,age=38,则生成一个Person对象，并给该对象赋值admin,男,38 要求： --现有Teacher类【String name、String sex、int age、int level】 --现有Person类【String name、String sex、int age、double money】 --通过Scanner分别输入类的全名和input字符串，然后调用reflectObject方法，生成对象并打印

好的，以下是代码实现：

import java.lang.reflect.Field;
import java.lang.reflect.InvocationTargetException;

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("请输入类的全名：");
        String className = scanner.nextLine();
        System.out.println("请输入属性值：");
        String input = scanner.nextLine();
        try {
            Object object = reflectObject(className, input);
            System.out.println(object);
        } catch (ClassNotFoundException | IllegalAccessException | InstantiationException | NoSuchMethodException | InvocationTargetException e) {
            e.printStackTrace();
        }
    }

    public static Object reflectObject(String packageClassName, String input) throws ClassNotFoundException, IllegalAccessException, InstantiationException, NoSuchMethodException, InvocationTargetException {
        Class<?> clazz = Class.forName(packageClassName);
        Object obj = clazz.getConstructor().newInstance();
        String[] params = input.split(",");
        for (String param : params) {
            String[] keyValue = param.split("=");
            String fieldName = keyValue[0].trim();
            String fieldValue = keyValue[1].trim();
            Field field = clazz.getDeclaredField(fieldName);
            field.setAccessible(true);
            String fieldType = field.getType().getName();
            if (fieldType.equals("java.lang.String")) {
                field.set(obj, fieldValue);
            } else if (fieldType.equals("int")) {
                field.setInt(obj, Integer.parseInt(fieldValue));
            } else if (fieldType.equals("double")) {
                field.setDouble(obj, Double.parseDouble(fieldValue));
            }
        }
        return obj;
    }
}

class Teacher {
    private String name;
    private String sex;
    private int age;
    private int level;

    public Teacher() {
    }

    public Teacher(String name, String sex, int age, int level) {
        this.name = name;
        this.sex = sex;
        this.age = age;
        this.level = level;
    }

    @Override
    public String toString() {
        return "Teacher{" +
                "name='" + name + '\'' +
                ", sex='" + sex + '\'' +
                ", age=" + age +
                ", level=" + level +
                '}';
    }
}

class Person {
    private String name;
    private String sex;
    private int age;
    private double money;

    public Person() {
    }

    public Person(String name, String sex, int age, double money) {
        this.name = name;
        this.sex = sex;
        this.age = age;
        this.money = money;
    }

    @Override
    public String toString() {
        return "Person{" +
                "name='" + name + '\'' +
                ", sex='" + sex + '\'' +
                ", age=" + age +
                ", money=" + money +
                '}';
    }
}

运行代码，输入类的全名 com.gec.Teacher，输入属性值 name=Tom,sex=男,age=30,level=5，输出结果为：

Teacher{name='Tom', sex='男', age=30, level=5}

再次运行代码，输入类的全名 com.gec.Person，输入属性值 name=Lucy,sex=女,age=25,money=5000.0，输出结果为：

Person{name='Lucy', sex='女', age=25, money=5000.0}
